ISL6545A Overview
® Data Sheet ISL6545, ISL6545A April 29, 2010 FN6305.5 5V or 12V Single Synchronous Buck Pulse-Width Modulation (PWM) Controller The ISL6545 makes simple work out of implementing a plete control and protection scheme for a DC/DC stepdown converter driving N-Channel MOSFETs in a synchronous buck topology. Since it can work with either 5V or 12V supplies, this one IC can be used in a wide variety of applications...
