ISL6562 TM Data Sheet March 2001 File Number 9012 Microprocessor CORE Voltage Regulator Two-Phase Buck PWM Controller The ISL6562 two-phase current mode, PWM control IC together with companion gate drivers, the HIP6601A, HIP6602A, HIP6603A or HIP6604 and MOSFETs provides a precision voltage regulation system for advanced microprocessors.

Two-phase power conversion is a marked departure from earlier single phase converter conﬁgurations previously employed to satisfy the ever increasing curre

FN9012 Features

* of this controller IC include programmable VID codes from the microprocessor that range from 1.050V to 1.825V with an accuracy of ±0.8%. Pull up currents on these VID pins eliminates the need for external pull up resistors. Another feature of this controller IC is the PWRGD monitor circuit which is
