Buck Converter - Low Voltage, Synchronization Capability 1.5 A, 260 kHz

The NCV51411 is a 1.5 A buck regulator IC operating at a fixed−frequency of 260 kHz. The device uses the V2 control architecture to provide unmatched transient response, the best overall regulation and the simplest loop compensation for today’s high−speed logic. The NCV51411 accommodates input voltages from 4.5 V to 40 V and contains synchronization circuitry.
