Product Summary
The ISL6324ACRZ is a dual PWM controller. It delivers high efficiency and tight regulation from two synchronous buck DC/DC converters. The ISL6324ACRZ supports hybrid power control of AMD processors which operate from either a 6-bit parallel VID interface (PVI) or a serial VID interface (SVI). The dual output ISL6324ACRZ features a multi-phase controller to support uniplane VDD core voltage and a single phase controller to power the Northbridge (VDDNB) in SVI mode. Only the multi-phase controller is active in PVI mode to support uniplane VDD only processors.
Parametrics
ISL6324ACRZ absolute maximum ratings: (1)Supply Voltage (VCC): -0.3V to +6.2V; (2)Supply Voltage (PVCC): -0.3V to +15V; (3)Absolute Boot Voltage (VBOOT): GND - 0.3V to GND + 36V; (4)Phase Voltage (VPHASE): GND - 0.3V to 15V (PVCC = 12), GND - 8V (<400ns, 20μJ) to 24V (<200ns, VBOOT-PHASE = 12V); (5)Upper Gate Voltage (VUGATE): VPHASE - 0.3V to VBOOT + 0.3V, VPHASE - 3.5V (<100ns Pulse Width, 2μJ) to VBOOT + 0.3V; (6)Lower Gate Voltage (VLGATE): GND - 0.3V to PVCC + 0.3V, GND - 5V (<100ns Pulse Width, 2μJ) to PVCC+ 0.3V; (7)Input, Output, or I/O Voltage: GND - 0.3V to VCC + 0.3V.
