NJW4133 Series
2.4MHz, 45V, 5A MOSFET Switching Regulator IC for Boost Converter
-
Description
The NJW4133 is a high speed oscillating frequency boost converter with 45V/5A MOSFET. Operating voltage range is wide input range from 3.0V to 40V, it can correspond to supply voltage drop such as cold crank. The NJW4133 has wide oscillating frequency range from 100kHz to 2.4MHz and external clock synchronization function. Therefore the NJW4133 can avoid interference with the AM radio frequency. Internal protection functions: UVLO, over voltage protection, over current protection and thermal shutdown circuit can protect IC when abnormal condition. The NJW4133 has wide coverage in consumer electronics and industrial application, because of features that are wide input operating voltage range and wide oscillating frequency range.
* Automotive: AEC-Q100 grade 1 in progress
