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 efficiency. The NCV91300 is housed in low profile 3.0 x 3.0 mm QFNW-16 package.
