LED Driver Demonstrates Low Dropout
Serving LED indicators and LCD or keyboard backlighting in entry-level mobile products, AnalogicTech’s AHK3292 2-channel LED driver (SSLD) has a typical dropout voltage of 36 mV. Operating off an input supply from 2.7 V to 5.5 V, the component drives up to 2 LEDs. The SSLD exhibits a maximum LED current of 30.2 mA with ±10% LED output current accuracy and ±3% LED output current matching. An S²Cwire interface enables, disables, and controls the output current for each LED. The 6-pin, SOT23-packaged device offers a low-current shutdown mode, and is qualified from -40ºC to 85ºC. Pricing is $0.39 in 1,000 quantities.
