DEMO MANUAL DC2007A-B LTM4630EV High Efficiency, PolyPhase 105A Step-Down Power Module Regulator DESCRIPTION Demonstration circuit 2007A-B features a PolyPhase(R) design using the LTM(R)4630EV, the high efficiency, high density, dual 18A, switch mode step-down power Module(R) regulator. The input voltage is from 4.5V to 15V. The output voltage is jumper selectable from 0.9V to 1.8V. The DC2007A-B can deliver a nominal 105A output current. As explained in the data sheet, output current derating is necessary for certain VIN, VOUT, and thermal conditions. The LTM4630 on DC2007A-B always operates in continuous conduction mode. The switching frequency can be programmed through a resistor or can be synchronized to an external clock signal. The board allows the user to program how its output voltage ramps up and down through the TRACK pin. The output voltage is tightly regulated between "VO+" and "VO-" through remote output voltage sensing which improves output voltage regulation at heavy loads. These features and the availability of the LTM4630EV in a compact 16mm x 16mm x 4.41mm LGA package make it ideal for use in many high density point-of-load regulation applications. The LTM4630 data sheet must be read in conjunction with this demo manual for working on or modifying the demo circuit DC2007A-B.

Figure 1. 70A PolyPhase LTM4630/DC2007A-B Demo Board dc2007a_bf 1 DEMO MANUAL DC2007A-B PERFORMANCE SUMMARY PARAMETER Specifications are at TA = 25C CONDITIONS / NOTES VALUE Input Voltage Range 4.5V ~ 15V Output Voltage VOUT VIN = 4.5A ~ 15V, IOUT = 0A ~ 105A, JP5: 1.0V 1.0V 1.5% (0.985V ~ 1.015V) Maximum Continuous Output Current Derating Is Necessary for Certain VIN, VOUT and Thermal Conditions, See Data Sheet for Details. 105A Default Operating Frequency 400kHz Resistor Programmable Frequency Range 400kHz to 780kHz External Clock Sync. Frequency Range 400kHz to 780kHz VIN = 12V, VOUT = 1.0V, IOUT = 105A, fSW = 400kHz Efficiency 83.8% See Figure 3 Load Transient VIN = 12V, VOUT = 1.0V, ISTEP = 0A ~ 26.25A <100mV, See Figure 4 Output Voltage Ripple VIN = 12V, VOUT = 1.0V, IOUT = 105A <4mV, See Figure 5 QUICK START PROCEDURE Demonstration circuit DC2007A-B is easy to set up to evaluate the performance of PolyPhase operation of the LTM4630EV. Due to the high input/output current, user should select the proper input supply/load/cable which can sustain the full load operation. It's recommended to pull load current from J2 and J4. The load current pulled from J5 and J6 shouldn't exceed 18A. Please refer to Figure 2 for proper measurement setup and follow the procedure below: 1. Place jumpers in the following positions for a typical 1.0VOUT application: JP1 JP2 JP4 ~ JP8 CLK RUN VOUT SELECT INT OFF ON JP5/1.0V 2. With power off, connect the input power supply, load and meters as shown in Figure 2. Preset the load to 0A and VIN supply to 12V. 3. Turn on the power supply at the input. Place JP2 to the ON position. The output voltage between "VO+" and "VO-" should be 1.0V 1.5% (0.985V ~ 1.015V). 5. (Optional) For an optional load transient test, apply an adjustable pulse signal between "IOSTEP CLK" and the "GND" test point. Pulse amplitude (3V ~ 3.5V) sets the load step current amplitude. The output transient current can be monitored at the BNC connector, J8 (5mV/A). The pulse signal should be very small duty cycle (<10%) to limit the thermal stress on the transient load circuit. 6. (Optional) The LTM4630 can be synchronized to an external clock signal. Place the JP1 jumper on EXT and apply a clock signal (0V ~ 5V, square wave) on the "EXT_CLK" test point. 7. (Optional) The outputs of the LTM4630 can track another supply. The output voltage tracks the voltage on TRACK when a valid signal is applied on the test point. 8. (Optional) The DC2007A-B can be configured to a dual output configuration with VO at 87.5A load current and VO2 at 18A load current. Stuff a 0 resistor on R61 and a 0.1F on C14. Remove R22, R23, R24, R26, R27, R28, R32, R33, R35. Output voltage VO2 is set by R37 based on the equation VO2 = 0.6V(1 + 60.4K/R37). 4. Once the proper output voltage is established, adjust the load within the operating range and observe the output voltage regulation, output voltage ripple, efficiency and other parameters. Output voltage ripple should be measured at J7 with BNC cables. 50 termination should be set on the oscilloscope or BNC cables. dc2007a_bf 2 DEMO MANUAL DC2007A-B QUICK START PROCEDURE Figure 2.
