Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ALT80802KEJJTR is a high-frequency switching regulator that provides constant output current to drive high-power LEDs providing constant output current. It integrates a power MOSFET for buck or inverting boost conversion. Fast transient response is achieved through current mode control and simple external compensation, and a wide input range of 3.8 to 50 V makes the device suitable for a variety of lighting applications, including those in automotive input environments. The device's rating also provides a simple solution for driving 3 to 4 WLEDs in a buck configuration - a very common application requirement in automotive lighting applications.
