NJW4131 Datasheet Switching Regulator

Manufacturer: New Japan Radio

Overview: NJW4131 Switching Regulator IC for Boost Converter w/ 40V/1.

Datasheet Details

The NJW4131 is a boost converter with 40V/1.4A or 40V/1A MOSFET.

It corresponds to high oscillating frequency, and Low ESR Output Capacitor (MLCC) within wide input range from 4.0V to 35V.

Therefore, the NJW4131 can realize downsizing of an application with a few external parts.

Output Switch Voltage 40V max. Wide Operating Voltage Range 4V to 35V Switching Current 1.4A (min. ) @ A version 1.0A (min. ) @ B version PWM Control Wide Oscillation Frequency 300kHz to 1MHz Soft-Start Function 4ms typ. UVLO (Under Voltage Lockout) Over Current Protection / Thermal Shutdown Protection Standby Function Package Outline NJW4131GM1: HSOP8 NJW4131R: MSOP8(VSP8).
