ISL6267 - Multiphase PWM Regulator

Features

  • Both outputs support DCR current sensing with a single NTC thermostat for DCR temperature compensation or accurate resistor current sensing. Both of the outputs utilize remote voltage sense, adjustable switching frequency, current monitor, OC protection, independent power-good indicators, temperature monitors, and a common thermal alert.

DATASHEET ISL6267 Multiphase PWM Regulator for AMD Fusion™ Mobile CPUs FN7801 Rev 1.00 Jan 8, 2013 The ISL6267 is designed to be completely compliant with AMD Fusion™ specifications. The ISL6267 controls two Voltage Regulators (VRs), with three integrated gate drivers. The first VR can be configured as 3-, 2-, or 1-phase VR, while the second output can be configured as 2- or 1-phase VR, providing maximum flexibility. The two VRs share the serial control bus to communicate with the CPU and achieve lower cost and smaller board area compared with two-chip solutions. The PWM modulator of the ISL6267 is based on Intersil’s R3 (Robust Ripple Regulator) Technology™.
