NCV8842

1.5 A, 170 kHz, Buck

Regulator with

Synchronization Capability

The NCV8842 is a 1.5 A buck regulator IC operating at a

fixed−frequency of 170 kHz. The device uses the V t 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.
