Product details

Where it fits in the BOM

This controller is a fit for automotive power supplies that need a regulated boost or SEPIC rail from a battery bus. The 93% max duty cycle allows high step-up ratios, and the clock sync input lets multiple converters share a common switching frequency to manage EMI. The part is active with no end-of-life notice, so it is safe to specify for new production BOMs.

Sourcing posture

No LTB window or successor part has been announced, so there is no immediate supply risk for production builds.

Frequently asked questions
