The internal switch is rated for 750 mA peak current, which sets the maximum LED string current before the inductor saturates or the switch overheats. Dimming is controlled via PWM on the enable pin, allowing the LED current to be chopped at a duty cycle that the human eye integrates as brightness. The 1.2 MHz switching frequency is well above audible range, so no coil whine reaches the camera microphone during flash recharge. The single-output channel drives a series LED string; the 34 V compliance means up to 8–10 white LEDs in series (at ~3.2 V each) can be biased from a single Li-ion cell. The 750 mA switch current is the peak inductor current, not the average LED current — the actual LED current depends on the sense resistor and the boost ratio. ## Package and temperature grade Surface-mount assembly with the 2x2 mm MLF footprint — the exposed pad must be soldered to the ground plane for both thermal and electrical connection. The package is RoHS-compliant per Microchip's standard material declaration.","metaTitle":"MIC2287C-24YMLTR Boost LED Driver, 34V, 1.2MHz, PWM Dimming","metaDescription":"Microchip Technology MIC2287C-24YMLTR DC-DC boost regulator, 34V output, 750mA switch, 1.2MHz PWM dimming.
