Abstract: For automotive lighting and decorative light strips, a complete lighting driver solution is provided by combining 30-100V power MOS with DC-DC power chips.

Application Overview
The working environment of LED automotive lighting and decorative light strips is complex, requiring them to withstand wide voltage inputs and frequent switch disturbances. The power drive circuit has high standards for device voltage resistance, heat dissipation, anti-interference, and long-term reliability. MOSFET and power chip are the core of constant current drive and circuit switch, directly affecting the stability of light output and the service life of lamps.
Huaxin Er is targeting the LED lighting market and has launched 30-100V power MOSFETs, which are suitable for driving circuits in automotive lighting and various decorative light strips. Low on resistance of the device reduces overall heat generation; Excellent avalanche resistance, able to withstand voltage surges under working conditions; Rich packaging options, balancing high-power heat dissipation and compact board layout requirements. Equipped with DC-DC power chips, it can achieve constant current output, integrate multiple protections for overcurrent and over temperature, and help customers simplify peripheral circuits.
Equipped with Schottky, TVS, and ESD protection devices, covering the entire driving, rectification, and protection chain, providing a complete domestic device solution for automotive and civilian lighting.
