IRDC3073EVAL
IRU3073 EVALUATION BOARD USER GUIDE
INTRODUCTION
SPECIFICATION DATA
The IRU3073 controller IC is designed to provide a low
cost synchronous Buck regulator for on-board DC to DC
converter for multiple output applications.
The outputs can be programmed as low as 0.8V for low
voltage applications.
Selectable over-current protection is provided by using
external MOSFET's on-resistance for optimum cost and
Switcher:
V IN = 5V
V OUT1 = 2.5V
I OUT1 = 8A
D V OUT = 50mV
F S = 200KHz
Linear
Regulator:
V IN = 2.5V
(from switch)
V OUT2 = 1.6V
I OUT2 = 2A
Supply Voltage:
V CC = V C = 12V
performance.
This device features a programmable frequency set from
200KHz to 400KHz, under-voltage lockout for all input
supplies, an external programmable soft-start function
as well as output under-voltage detection that latches off
the device when an output short is detected.
INPUT/OUTPUT CONNECTIONS
The following is the input/output connections:
Inputs:
JP3: Input (+5V), Gnd
JP1: Input (+12V)
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:
JP4: V OUT1 (+2.5V), Gnd
JP2: V OUT2 (+1.6V), Gnd
Note: For proper operation, +5V supply should ramp up first.
