The 20-A family of programmable ISRs incorporate a pin- coded control to adjust the output voltage. This feature uses the control pins VIDO-VID4 (pins l-6). When the control pins are left open-circuit, the ISR output regulates at its default output voltage. Each control pin is internally connected to a precision resistor, which when grounded applies a weighted change to the output voltage. By selectively grounding VIDO-VID4, the output voltage of these ISRs can be programmed in incremental steps over the module's output voltage range. The program codes and output voltage range offered by these ISRs are compatible with the Voltage ID specifications defined by Intel Corporation for VRMs (voltage regulator mod- ules). The codes are used by both the Pentium~ and Athlon~ microprocessors. Refer to Figure l for the connecoon schematic, and the respective device Data Sheet for the programming code information.
