2channel MOSFET Drive Switching Regulator IC for Buck Converter
The NJW4162A is a 2 channel MOSFET Drive switching regulator IC for buck converter that operates wide input voltage range from 4.3V to 40V. The oscillating frequency range can set within 100kHz to 1MHz by external resistor. It also has an external synchronous function. It has individual Standby functions, Soft Start functions and Power Good functions for each channel, therefore a start-up control and/or operating condition monitoring are available with a microcomputer. The NJW4162A is suitable for a logic voltage generating circuit from high input voltage such as Automotive. Office Automation and Industrial applications.
