CS51311 Datasheet (ON Semiconductor) - Synchronous CPU Buck Controller

CS51311, Synchronous CPU Buck Controller

PACKAGE PIN # SO *14 1, 2, 3, 4, 5 PIN SYMBOL VID0 *VID4 FUNCTION Voltage ID DAC inputs.

These pins are internally pulled up to 5.65 V if left open.

VID4 selects the DAC range.

When VID4 is high (logic one), the Error Amp reference range is 2.125 V to 3.525 V with 100 mV increments.
