Switching Regulator IC For Buck Converter Current Mode Control

Manufacturer's part number :

NJW4153KV1

Manufacturer New Japan Radio

New Japan Radio

Description :

The NJW4153 is a buck converter with 40V/1A MOSFET. It corresponds to high oscillating frequency, and Low ESR Output Capacitor (MLCC) within wide input range from 4.6V to 40V.Therefore, the NJW4153 can realize downsizing of applications with a few external parts so that adopts current mode control. Also, it has a soft start function, an over current protection and a thermal shutdown circuit. It is suitable for power supply circuit of Micro Processor, DSP and so on that need fast transient response.
