The NCV6357 is a synchronous AOT (Adaptive On−time) buck

converter optimized to supply the different sub systems of automotive

applications post regulation system up to 5 V input. The device is able

to deliver up to 5.0 A, with programmable output voltage from 0.6 V

to 3.3 V. Operation at up to 2.4 MHz switching frequency allows the

use of small components. Synchronous rectification and automatic

PFM Pseudo−PWM (PPWM) transitions improve overall solution

efficiency. The NCV6357 is in low profile 3.0 × 4.0 mm DFN−14 package.
