Power Good
1. This module has a power good indicator output. Power good pin used positive logic and is open collector.
2. Power good pin can sink 10mA.
3. The maximum voltage pulled up externally on Power Good pin should not exceed 6V.
4. When a successful soft-start is completed, the power good pin will be pulled high.
CH1: Output Voltage CH2: Remote ON/OFF CH3: PG
Typical Start-up Using Remote ON/OFF(Vin=12.0V, Vout=1.5V, Io=90A)
IMON Diagram
Note: The IMON pin is the average channel-current sense output. This pin is used as a load current indicator to
monitor the output load current. When Iout = 90A the voltage on the IMON pin = 900mV.
