Datasheet Summary
55V Synchronous Buck Controller with Integrated 3A Driver
FN8657 Rev 3.00 December 12, 2014
The ISL78268 is a grade 1, automotive, synchronous buck controller with integrated high/low side MOSFET drivers. It supports a wide operating input voltage range of 5V to 55V and up to 60V at VIN when not switching. The integrated driver offers adaptive dead-time control and is capable of supplying up to 2A sourcing and 3A sinking current, allowing the ISL78268 to support power stages designed for a wide range of loads, from under 1A to over 25A.
ISL78268’s fully synchronous architecture enables power conversion with very high efficiency and improved thermal performance over...
