ISL6353
Multiphase PWM Regulator for VR12 DDR Memory Systems
FN6897 Rev 0.00 September 15, 2011
The ISL6353 is a three-phase PWM buck regulator controller for VR12 DDR memory applications. The multi-phase implementation results in better system performance, superior thermal management, lower component cost and smaller PCB area.
The ISL6353 has two integrated power MOSFET drivers for implementing a cost effective and space saving power management solution.
The PWM modulator of the ISL6353 is based on Intersil’s Robust Ripple Regulator™ (R3) technology. Compared with the traditional multi-phase buck regulator, the R3 modulator commands variable PWM switching frequency during load transients, achieving faster transient response.
