The NJW4161 is a MOSFET Drive switching regulator IC for Buck Converter that operates wide input range from 3.1V to 40V.

It can provide large current application because of built-in highly effective Pch MOSFET 10V drive circuit.

There are two types, Hiccup type and Latch type, of over current protection version.

Pch MOSFET Driving Driving Voltage V+-10V(typ. ) Wide Operating Voltage Range 3.1V to 40V PWM Control Automatic PWM/PFM Control improves power efficiency at light load. (C ver. ) Wide Oscillating Frequency 50kHz to 1MHz Soft Start Function 15ms (typ. ) Over Current Protection Hiccup type (A, C ver. ) Latch type (B ver. ) Thermal Shutdown Protection UVLO (Under Voltage Lockout) Standby Function Package Outline NJW4161R: MSOP8(VSP8).
