ISL78264 Description
ISL78264 Automotive Dual Synchronous Buck Controller with Integrated Drivers Datasheet The ISL78264 is a dual buck controller that can operate across a wide VIN range of 3.75V to 42V. It is designed to support wide duty-cycle operation for switching frequencies from 200kHz up to 2.2MHz. To mitigate EMI, it supports synchronization to an external clock or programmable spread spectrum clocking.
