The APM80904 is an automotive-grade, low-EMI, 1.5 A synchronous buck LED driver module integrating high-side and low-side MOSFETs, an inductor, and input capacitors. It operates from a 4.5 V to 36 V supply, with a maximum of 40 V, and delivers up to 1.5 A output current. The device features PWM and analog dimming, programmable internal PWM, and a 5 V, 14 mA LDO regulator. Protected by AEC-Q100 qualification, it is housed in a 4 mm × 6 mm × 2.1 mm QFN-32 package with wettable flanks and includes fault flag output, UVLO, and thermal shutdown. Efficiency reaches 90% at 1 A with 80 mΩ and 60 mΩ MOSFETs.
The APM80900/4 simplifies automotive LED lighting design with an integrated inductor, high-side and low-side MOSFETs, and cycle-by-cycle current control for precise LED current regulation. Offers flexible dimming options (PWM, analog) and comprehensive protection. The APM80904 includes programmable internal PWM dimming.
