The datasheet introduces the features and usage of AP8800 350mA LED Step-down Converter. The AP8800 is a constant current LED driver that can drive 12V to 28V voltage sources with a maximum output current of 350mA. The device features high efficiency, high switching frequency, PWM/DC input, and soft-start function.
The AP8800 LED step‑down converter provides a constant‑current drive for up to seven LEDs in series, handling input voltages from 8 V to 28 V and delivering up to 350 mA with up to 92 % efficiency. It features PWM/DC dimming, soft‑start, open‑circuit protection, and is offered in SOP‑8L, MSOP‑8L and DFN3030‑10 packages.
Typical applications include commercial and industrial lighting, LCD panel backlights, architectural lighting and interior appliance lighting. The device is configured by an external resistor on the SET pin, and the output current can be adjusted via a PWM signal on the CTRL pin. Recommended external components include a 100 µH inductor, 1 µF ceramic input capacitor, and a Schottky diode such as B140.
