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 compensation 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.
It is suitable for supplying power to a Car Accessory, Audio
Automation Equipment, Industrial Instrument and so on.
