1.5 A, 340 kHz, Buck
Regulator with
Synchronization Capability
The NCV8843 is a 1.5 A buck regulator IC operating at a
fixedfrequency of 340 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 NCV8843 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.
