The ISL6218 Single-Phase Buck PWM control IC, with integrated half bridge gate driver, provides a precision
voltage regulation system for advanced Pentium-M microprocessors in notebook computers.
This control IC also features both input
voltage feed-forward and average current mode control for excellent dynamic response, “Loss-less” current sensing using
MOSFET rDS(ON), and user selectable switching frequencies from 250kHz to 500kHz per phase.
The ISL6218 includes a 6-bit digital-to-analog converter (DAC) that dynamically adjusts the CORE ...
