NJW4160

NJW4160 Switching Regulator IC for Buck Converter External MOSFET driving GENERAL DESCRIPTION The NJW4160 is a MOSFET Drive switching regulator IC for Buck Converter that operates wide input range from 3.0V to 35V. It can provide large current application because of built-in highly effective Pch MOSFET drive circuit. Built-in pulse-by-pulse current detecting type over current protection limits the output current at over load. It is suitable for logic voltage generation from high voltage that Car Accessory, Office Automation Equipment, Industrial Instrument and so on. ■ PACKAGE OUTLINE NJW4160R (MSOP8(VSP8)) NJW4160M (DMP8) FEATURES Pch MOSFET Driving Wide Operating Voltage Range PWM Control Wide Oscillating Frequency Over Current Protection UVLO (Under Voltage Lockout) Standby Function Package Outline Driving Voltage V+-5.35V(typ.) 3V to 35V 50kHz to 1MHz NJW4160M: DMP8 NJW4160R: MSOP8(VSP8) *MEETJEDEC MO-187-DA PIN CONFIGURATION 1 2 3 4 NJW4160R NJW4160M 8 7 6 5 PIN FUNCTION 1.
