NCV8842中文资料Buck Regulator, 1.5 A, 170 kHz, with Synchronization Capability数据手册ONSEMI规格书

描述 Description

The NCV8842 is a 1.5 A buck regulator IC operating at a fixed frequency of 170 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.
