ISL6336B 6-Phase PWM Controller

® Data Sheet August 31, 2010 ISL6336B FN6696.2 6-Phase PWM Controller with Light Load Efficiency Enhancement and Current Monitoring The ISL6336B controls microprocessor core voltage regulation by driving up to 6 interleaved synchronous-rectified buck channels in parallel. Multiphase buck converter architecture uses interleaved timing to multiply channel ripple frequency and reduce input and output ripple currents. Lower ripple results in fewer components, lower component cost, reduced power d.

ISL6336B Features

* include a pin (IMON) for current monitoring and a Power State Indicator (PSI#) input pin to initiate a proprietary phase dropping and diode emulation scheme for higher efficiency at light load by dropping to 1- or 2-phase operation with optional diode emulation to reduce switching and core losses in
