... Remote output voltage sense Non-latching overload and short circuit protection Crow-bar output overvoltage protection DESCRIPTION The GS-R400 series is a versatile family of high current, high voltage step-down switching voltage regulators. The integral heatsink allows a large power handling capability and it provides also an effective shielding to minimize EMI ...

... Return for input voltage source. 4 100kHz oscillator output connected to Sync (pin 6) input if the unit is a master and Oscillator 5 left open slave (GS-R400VB only). See fig. 5. Sync Synchronization input connected to the Oscillator output (pin 5) of the master (GS- 6 R400VB only). See fig. 5. ...

... 5mA 10mA Case to ambient Thermal Characteristics The case-to-ambient thermal resistance of all the GS-R400 modules is about 5 C/W. This produces temperature increase of the module surface for 10W of internal power dissipation. Depending on the ambient temperature and/or on the power dissipation, an additional heatsink or forced ventilation may be required ...

... R 2.67 v 5.1 V can be adjusted between 5.1 and 40V. o Current Limiting Programming The GS-R400VB current limiting is programmed by using a resistor (see pin function table and fig. 4). Figure 1. Load Connection Figure 2. Remote Inhibit Operation 4/5 The value of the resistor is calculated by using the following formula: Module Protection The modules are protected against occasional and permanent short circuits of the output pin to ground, as well as against output current overload ...
