NJW4162A
2channel MOSFET Drive Switching Regulator IC for Buck Converter
GENERAL DESCRIPTION
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.
