GS-R400/2 series is a family of high current, high voltage step-down switching regulators. The series has 4A max output current, 40V max input voltage, 4V max dropout voltage, soft start, non-latching short circuit protection, crow-bar output overvoltage protection etc.
The GS-R400/2 series is a family of small sized, high current, high voltage step-down switching regulators. The integral heatsink allows for large power handling capability and provides effective shielding to minimize EMI. The family includes fixed output voltage types and a programmable output voltage version (GS-R400V/2).
| Max Output Current | 4 A |
|---|---|
| Max Input Voltage | 40 V |
| Max Dropout Voltage | 4 V |
| Thermal Resistance (Case to Ambient) | 8 °C/W |
| MTBF | 500,000 hours |
The recommended operating maximum DC input voltage is 40V inclusive of the ripple voltage.
The output voltage is programmed by using a resistor connected between the Program pin and the Output pin.
The output is automatically disabled, and after a fixed time the module starts again in a soft mode.
