Evaluation Board for Peripheral Power Controller for Pentium® 4 Computer Systems


The HIP6521EVAL1 evaluates the HIP6521 PWM and triple linear power controller. This evaluation board embodies a 4-output regulator solution targeted at supplying power to the system memory (2.5V), system clock (2.5V), ICH/MCH chip set core (1.8V), and the 4X AGP video (1.5V), with provisions for ACPI power management implementation.

The HIP6521 was created to complement a multiphase buck controller in creating a complete power solution for the typical Pentium 4 system. Athlon-class processor based systems (AMD) may also benefit from the HIP6521.
