ISL78225 Overview
DATASHEET ISL78225 4-Phase Interleaved Boost PWM Controller with Light Load Efficiency Enhancement FN7909 Rev 4.00 September 5, 2014 The ISL78225 4-phase controller is targeted for applications where high efficiency (>95%) and high power are required. The multiphase boost converter architecture uses interleaved timing to multiply channel ripple frequency and reduce input and output ripple. Lower ripple results in...
