Datasheet Summary
NJW4170
Current Mode Control High Speed Frequency Internal 1A MOSFET Switching Regulator IC for Buck Converter
GENERAL DESCRIPTION
The NJW4170 is a high speed oscillating frequency buck converter with 40V/1A MOSFET. Current mode control and built-in phase pensation circuit minimize external parts and contribute to using a Low ESR Output Capacitor(MLCC) within wide input range from 4.5V to 40V. Therefore, the NJW4170 can realize downsizing of applications.
Also, it has a soft start function, an external clock synchronization function, an over current protection and a thermal shutdown circuit.
Over 2MHz of Switching frequency can avoid interference with the AM radio frequency.
