NJW4153 fiche technique
Automotive NJW4153
Switching Regulator IC for Buck Converter
Current Mode Control w/ 40V/1A MOSFET
GENERAL 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.
