AEE-10W 12V input converters have a 2:1 input voltage range of 9-18V. Care should be taken to avoid applying reverse polarity to the input which can damage the converter. Trim Fig.1. Pins Series Fuse Rating 12Vin 4A Input Reverse Voltage Voltage Protection Under installation and cabling conditions where reverse polarity across the input may occur, reverse polarity protection is recommended. Protection can easily be provided as shown in Figure 2. In both cases the diode rating is determined by the power of the converter. Diodes should be rated at 5A/25V for the AEE-10W 12Vin single output series. Placing the diode across the inputs rather than in-line with the input offers an advantage in that the diode only conducts in a reverse polarity condition, which increases circuit efficiency and thermal performance. Input Characteristic Fusing: The AEE-10W 12V input power module has no internal fuse. An external fuse must always be employed! To meet international safety requirements, a 250 Volt rated fuse should be used. If one of the input lines is connected to chassis ground, then the fuse must be placed in the other input line. Standard safety agency regulations require input fusing. Recommended fuse ratings for the AEE-10W 12Vin Series are shown in Table 1.

To reduce reflected noise, a capacitor can be added across the input as shown in Figure 3, forming a filter. A 47F/25V electrolytic capacitor is recommended for C1. +Vin C1 -Vin Fig.3. Ripple Rejection Input Filter For conditions where EMI is a concern, a different input filter can be used. Figure 4 shows an input filter designed to reduce EMI effects. L1 is a 12 H differential inductor, C1 is a 47F/25V electrolytic capacitor, and C0 is a 1F/25V metal film or ceramic high frequency capacitor. When a filter inductor L1 is connected in series with the power converter input, an input capacitor C0 should be added. An input capacitor C0 should also be used when the input wiring is long, since the wiring can act as an inductor. Failure to use an input capacitor under these conditions can produce large input voltage spikes and an unstable output. L1 C0 +Vin C1 -Vin Fig.4.

To turn the power module on or off, the user must supply a switch to control the voltage on the CNT pin, the switcher may be an open collector or equivalent (see Fig.5.). The logic low is Von/off = 0 V to +0.7V. The logic high is Von/off = +3.6V to +6V. The module does not have internal capacitance to reduce noise at the CNT pin. Additional capacitance is needed. A 1uF/25V electrolytic capacitor is recommended for C1. Vi(+) 5V C1 Vi(-) CNT Vcnt: ON--- Vcnt = 0 ~ +0.7V or CNT pin in midair OFF--- Vcnt = +3.6V ~ +6V C1: Recommended 1mF/25V Fig.5. Remote ON/OFF Control Input-Output Characteristic Isolation: The isolation voltage between input to output, input to case and case to output are all greater than 1500 Volt DC. If the system using the power module needs to meet safety agency approval, certain rules must be followed in the design of the system using the module. In particular, all of the creepage and clearance requirements of the end-use safety requirement must be observed.

The input-to-output 1500VDC isolation is an operational insulation. The DC/DC power module should be installed in end-use equipment, in compliance with the requirements of the ultimate application, and is intended to be supplied by an isolated secondary circuit. When the supply to the DC/DC power module meets all the requirements for SELV(<60Vdc), the output is considered to remain within SELV limits (level 3). If connected to a 60Vdc power system, double or reinforced insulation must be provided in the power supply that isolates the input from any hazardous voltages, including the ac mains. One Vi pin and one Vo pin are to be grounded or both the input and output pins are to be kept floating. Single fault testing in the power supply must be performed in combination with the DC/DC power module to demonstrate that the output meets the requirement for SELV. The input pins of the module are not operator accessible. Note: Do not ground either of the input pins of the module, without grounding one of the output pins. This may allow a non-SELV voltage to appear between the output pin and ground.

The trim resistor should be positioned close to the module. If not using the trim feature, leave the TRIM pin open. Trimming up by more than 10% of the nominal output may damage the converter or trig the OVP protection. Trimming down more than 10% can cause the converter to regulate improperly.

The recommended component for C2 is 100F/25V capacitor and connecting a 0.47F/50V ceramic capacitor in parallel generally. Output Over-Current Protection: AEE-10W 12V input series DC/DC converters feature foldback current limiting as part of their Overcurrent Protection (OCP) circuits. When output current exceeds 110 to 150% of rated current, such as during a short circuit condition, the output will shutdown. Note if input voltage exceeds 20V, the continuous shortcircuit may damage the module or decrease its life. Decoupling Noise on the power distribution system is not always created by the converter. High speed analog or digital loads with dynamic power demands can cause noise to cross the power inductor back onto the input lines. Noise can be reduced by decoupling the load. In most cases, connecting a 10 F tantalum capacitor in parallel with a 0.1F ceramic capacitor across the load will decouple it. The capacitors should be connected as close to the load as possible. Output Filters When the load is sensitive to ripple and noise, an output filter can be added to minimize the effects. A simple output filter to reduce output ripple and noise can be made by connecting a capacitor across the output as shown in Figure 8. The recommended value for the output capacitor is 100F/25V. +Vout + Load C2 -Vout Ground Loops Ground loops occur when different circuits are given multiple paths to common or earth ground, as shown in Figure 10. Multiple ground points can slightly different potential and cause current flow through the circuit from one point to another. This can result in additional noise in all the circuits. To eliminate the problem, circuits should be designed with a single ground connection as shown in Figure 11. RLine Fig.8. Output Ripple Filter RLine +Vout ( -Vout ) Load Load RLine COM Extra care should be taken when long leads or traces are used to provide power to the load.

Such designs, sometimes called daisy chains, can be used for very low output currents, but are not normally recommended. The voltage across loads far from the source can vary greatly depending on the IR drops along the leads and changes in the loads closer to the source. Dynamic load conditions increase the potential problems. I1 + I2 + I3 I2 + I3 I3 RL2 RL1 RL3 +Vout Load 1 Load 2 Load 3 -Vout RG2 RG1 RG3 RL = Lead Resistance RG = Ground Lead Resistance Fig.12. Parallel Power Distribution Radial Power Distribution Radial power distribution is the preferred method of providing power to the load. Figure 13. shows how individual loads are connected directly to the power source. This arrangement requires additional power leads, but it avoids the voltage variation problems associated with the parallel power distribution technique. +Vout RL3 RL1 RL2 Load 1 RG1 Load 2 Load 3 RG2 RG3 -Vout design when a purely radial design is not feasible. +Vout RL3 RL1 Load 1 RG1 RL4 RL2 Load 2 Load 3 Load 4 RG2 RG3 -Vout RG4 RL = Lead Resistance RG = Ground Lead Resistance Fig. 14. Mixed Power Distribution Redundant Operation A common requirement in high reliability systems is to provide redundant power supplies. The easiest way to do this is to place two converters in parallel, providing fault tolerance but not load sharing. Oring diodes should be used to ensure that failure of one converter will not cause failure of the second. Figure 15 shows such an arrangement. Upon application of power, one of the converters will provide a slightly higher output voltage and will support the full load demand. The second converter will see a zero load condition and will "idle". If the first converter should fail, the second converter will support the full load. When designing redundant converter circuits, Shottky diodes should be used to minimize the forward voltage drop. The voltage drop across the Shottky diodes must also be considered when determining load voltage requirements. RL = Lead Resistance RG = Ground Lead Resistance +Vout Fig.13. Radial Power Distribution -Vout Load Mixed Distribution In the real world a combination of parallel and radial power distribution is often used. Dynamic and high current loads are connected using a radial design, while static and low current loads can be connected in parallel. This combined approach minimizes the drawbacks of a parallel TEL: FAX: USA 1-760-930-4600 1-760-930-0698 Europe 44-(0)1384-842-211 44-(0)1384-843-355 +Vout -Vout Fig. 15.

Normally power components are always put at the end of the airflow path or have the separate airflow paths. This can keep other system equipment cooler and increase component life spans. Soldering AEE-10W 12V input series converters are compatible with standard wave soldering techniques. When wave soldering, the converter pins should be preheated for 20-30 seconds at 110 C, and wave soldered at 260C for less than 10 seconds. When hand soldering, the iron temperature should be maintained at 425C and applied to the converter pins for less than 5 seconds. Longer exposure can cause internal damage to the converter. Cleaning can be performed with cleaning solvent IPA or with water.
