NCV8843 Buck Regulator Synchronous 1.5 A, 340 kHz The NCV8843 is a 1.5 A buck regulator IC operating at a fixed frequency of 340 kHz.

The device uses the V2t control architecture to provide unmatched transient response, the best overall regulation and the simplest loop compensation for today’s high speed logic.

The NCV8843 accommodates input voltages from 4.0 V to 40 V and contains synchronization circuitry.

The on chip NPN transistor is capable of providing a minimum of
