DC-DC Converter Features The ECLB60W series offer 60 watts of output power in a 2.05x1.20x0.4 inches copper packages. The ECLB60W series has a 4:1 wide input voltage range of 9-36 and 18-75VDC, and provides a precisely regulated output. This series has features such as high efficiency, 1500VDC of isolation and allows an ambient operating temperature range of -40C to 85C (de-rating above 45 C). The modules are fully protected against input UVLO (under voltage lock out), output over-current, over-voltage and over-temperature and short circuit conditions.

Applications 5.1 Operating Temperature Range 6.1 Recommended Layout PCB Footprints and Soldering Information The ECLB60W series converters can be operated by a wide ambient temperature range from -40 to 85 (de-rating above 45). The standard model has a copper case and case temperature can not over 105 at normal operating. The system designer or the end user must ensure that other components and metal in the vicinity of the converter meet the spacing requirements to which the system is approved. Low resistance and low inductance PCB layout traces are the norm and should be used where possible. Due consideration must also be given to proper low impedance tracks between power module, input and output grounds. The recommended footprints and soldering profiles are shown below. 5.2 Remote On/Off The remote on/off input feature of the converter allows external circuitry to turn the converter on or off. Active-high remote on/off is available as standard. The converter is turned on if the remote on/off pin is high (>3.5Vdc to 75 or open circuit). Setting the pin low (0 to <1.2Vdc) will turn the converter `off'. The signal level of the remote on/off input is defined with respect to "-Vin". If not using the remote on/off pin, leave the pin open (module will be on). 5.3 UVLO (Under Voltage Lock Out) Input under voltage lockout is standard on the ECLB60W unit. The unit will shut down when the input voltage drops below a threshold, and the unit will operate when the input voltage goes above the upper threshold. 5.4 Over Current Protection All models have internal over current and continuous short circuit protection. The unit operates normally once the fault condition is removed. At the point of current limit inception, the converter will go into hiccup mode protection. Note: Dimensions are in inches (millimeters) Le a d Fre e Wa ve S olde ring P rofile 5.5 Over Voltage Protection The over-voltage protection consists of a zener diode to limiting the out voltage. Te mpe ra ture ( C ) 300 5.6 Over-Temperature Protection (OTP) The ECLB60W series converters are equipped with non-latching over-temperature protection. If the temperature exceeds a threshold of 110C (typical) the converter will shut down, disabling the output. When the temperature has decreased the converter will automatically restart. The over-temperature condition can be induced by a variety of reasons such as external overload condition or a system fan failure. 250 200 150 100 50 0 0 50 10 0 15 0 Tim e (S e conds ) Note 1.

To avoid problems with loop stability source inductance should be low. Also, the input capacitors (Cin) should be placed close to the converter input pins to de-couple distribution inductance. However, the external input capacitors are chosen for suitable ripple handling capability. Low ESR capacitors are good choice. Circuit as shown in Figure 5 represents typical measurement methods for reflected ripple current. C1 and L1 simulate a typical DC source impedance. The input reflected-ripple current is measured by current probe to oscilloscope with a simulated. VFL is the output voltage at full load VNL is the output voltage at zero load The value of line regulation is defined as: Line.reg = VHL - VLL x100% VLL Where VHL is the output voltage of maximum input voltage at full load.

The output voltage trim range is 10%. (Single output models only) This is shown in Figure 7 and 8: Figure 5 Input Reflected-Ripple Test Setup 6.6 Test Set-Up The basic test set-up to measure parameters such as efficiency and load regulation is shown in Figure 6. When testing the modules under any transient conditions please ensure that the transient response of the source is sufficient to power the equipment under test. We can calculate the * +Vin +Vo Trim Efficiency R-Load * Load regulation and line regulation. The value of efficiency is defined as: R trim-up VO x IO = x 100% VIN x IIN Where VO is output voltage, IO is output current, VIN is input voltage, IIN is input current.

Safety & EMC 7.1 Input Fusing and Safety Considerations. The ECLB60W series converters have not an internal fuse. However, to achieve maximum safety and system protection, always use an input line fuse. We recommended a time delay fuse 10A for 24Vin models and 6A for 48Vin modules. Figure 10 circuit is recommended by a Transient Voltage Suppressor diode across the input terminal to protect the unit against surge or spike voltage and input reverse voltage.
