ISL6554
ISL6554 is Microprocessor CORE Voltage Regulator Using Multi-Phase Buck PWM Control Without Programmable Droop manufactured by Renesas.
feature
. The ISL6554 in bination with the HIP6601A, HIP6602A or HIP6603A panion gate drivers and Intersil MOSFETs form a plete 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.
A novel approach to current sensing is used to reduce overall solution cost. The voltage developed across the lower MOSFET’s parasitic on-resistance during conduction is sampled and fed back to the controller. This lossless current-sensing approach...
