IRU3137 EVALUATION BOARD USER GUIDE
INTRODUCTION
SPECIFICATION DATA
The IRU3137 controller IC is designed to provide a low
cost and high performance synchronous Buck regulator
for on-board DC to DC converter applications. The out-
put voltage can be set as low as 0.8V and higher voltage
can be obtained with an external voltage divider. High
peak current gate drivers provide fast switching transi-
tion for applications requiring high output current in the
range of 15A to 20A.
This device features an internal 200KHz oscillator, un-
der-voltage lockout for both Vcc and Vc supplies, an
external programmable soft-start function as well as out-
put under-voltage detection that latches off the device
when an output short is detected.
INPUT/OUTPUT CONNECTIONS
V IN = 5V
V OUT = 2.5V
I OUT = 15A
D V OUT = 75mV
F S = 200KHz
Supply Voltage:
V CC = V C = 12V
The following is the input/output connections:
Inputs:
JP1: Input (+5V), Gnd
JP4: Input (+12V), Gnd
The connection points is shown in Figure 1. Connect the
power supply cables according to this figure, minimize
wire lengths to reduce losses in the wire. Test point J1
provides easy connections for the oscilloscope voltage
probe to monitor the output voltage.
Outputs:
JP2: V OUT (+2.5V)
JP3: Gnd
Note: For proper operation, +5V supply should ramp up first.
