ISL78264ARZ - Renesas Electronics

Description: 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. Its current-mode modulator is ideally suited to tolerate severe line transients. Also, the ISL78264 supports dropout operation and low 25ns on-time to operate through automotive cranking and load dump pu
