Buck Switching Regulator with Voltage Correction Circuit
NJW4119 Series
Buck Switching Regulator with Voltage Correction Circuit
-
Description
The NJW4119 is a buck switching regulator with voltage correction circuit that delivers up to 2.4 A of output current. The voltage correction (cable drop compensation) raises the output voltage in proportion to the load current. This function corrects the voltage drop due to cable or writing board resistance. Unique features, such as soft-start, power-good output and error flag output make the NJW4119 ideal for portable devices charged with USB cable.
Applications
- Car Infotainment
- USB Chargers
