The NCV8843 is a 1.5 A buck regulator IC operating at a fixed frequency of 340 kHz. The device employs the V2? control architecture to provide unmatched transient response, the best overall regulation and the simplest loop compensation. 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 short-circuit protection.
