Configurable 3.0 A PWM Step Down Converter NCV91300 The NCV91300 is a synchronous PWM buck converter optimized to supply the different sub systems of automotive applications post regulation system from 2.0 V up to 5 V input.

The device is able to deliver up to 3.0 A, with programmable output voltage from 0.6 V to 3.3 V.

Operation at up to 2.15 MHz switching frequency allows the use of small components.

Synchronous rectification and automatic PFM PWM transitions improve overall solution
