Overview

NCP1546 1.
5 A, 170 kHz, Buck Regulator with Synchronization Capability The NCP1546 is a 1.
5 A buck regulator IC operating at a fixed−frequency of 170 kHz.
The device uses the V2t control architecture to provide unmatched transient response, the best overall regulation and the simplest loop compensation for today’s high−speed logic.
The NCP1546 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 cu...
