ISL6560CBZ

DC DC Switching Controllers Overview

The ISL6560CBZ is a two-phase current mode PWM controller designed for microprocessor core voltage regulation. It operates with companion gate drivers and MOSFETs to provide precision voltage control. The device supports programmable VID codes ranging from 1.100V to 1.850V with an accuracy of ±0.8%. It utilizes high-side current sensing via a single sampling resistor in the input line to ensure excellent current sharing between phases. The controller features a PWRGD monitor and pull-up currents on VID pins, eliminating the need for external pull-up resistors.
