Microprocessor CORE Voltage Regulator Using Multi-Phase Buck PWM Control Without Programmable Droop
DATASHEET
FN9003 Rev 3.00 February 11, 2005
The ISL6554 is the first controller in the Intersil Multi-Phase family without the programmable droop feature. The ISL6554 in combination with the HIP6601A, HIP6602A or HIP6603A companion gate drivers and Intersil MOSFETs form a complete solution for high-current, high slew-rate applications. The ISL6554 regulates output voltage, balances load currents and provides protective functions for two to four synchronous-rectified buck-converter channels.
