NCV51411
1.5 A, 260 kHz, Low Voltage
Buck Regulator with
Synchronization Capability
The NCV51411 is a 1.5 A buck regulator IC operating at a
fixedfrequency of 260 kHz. The device uses the V
2
architecture to provide unmatched transient response, the best overall
regulation and the simplest loop compensation for today’s highspeed
logic. The NCV51411 accommodates input voltages from 4.5 V to
40 V and contains synchronization circuitry.
The onchip NPN transistor is capable of providing a minimum of
1.5 A of output current, and is biased by an external “boost” capacitor
to ensure saturation, thus minimizing onchip power dissipation.
Protection circuitry includes thermal shutdown, cyclebycycle
current limiting and frequency foldback. The NCV51411 is
functionally pincompatible with the LT1375.
