Datasheet SummaryAI
# GS-R400/2 Family Step-Down Switching Regulator

## Features
· MTBF exceeding 500,000 hours
· 4A max output current
· 40V max input voltage
· 4V max drop-out voltage
· Soft start
· Non-latching short circuit protection
· Crow-bar output overvoltage protection

## Electrical Characteristics
· Input Voltage: Up to 40V
· Output Voltage (Fixed): 5.1V, 12V, 15V, 24V
· Output Voltage (Programmable): 5.1V to 24V (GS-R400V/2)
· Output Ripple: 25mVpp to 100mVpp
· Switching Frequency: 100 kHz
· Thermal Resistance (Case to Ambient): 8°C/W

## Absolute Maximum Ratings
· DC Input Voltage (Vi): 42V
· Output Current (Io): 4A
