The NCV8842 is a 1.5 A buck regulator IC operating at a fixed−frequency of 170 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 NCV8842 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 1.5 A of output current, and is biased by an external “boost” capacitor to ensure saturation, thus minimizing on−chip power dissipation.Protection circuitry includes thermal shutdown, cycle−by−cycle current limiting and frequency foldback.
