Boost LED driver for backlight strings
The MIC2292-15YML-TR is a fixed-frequency step-up (boost) DC-DC regulator designed to drive LED strings from a low-voltage rail — typical for backlighting small LCD panels in portable or industrial gear where the LED forward voltage exceeds the supply. Its internal switch handles up to 750 mA, and the 1.6 MHz switching frequency keeps the inductor and output capacitor small enough for compact layouts.
Dimming and temperature range
Both analog and PWM dimming are supported — PWM dimming gives a wider effective contrast ratio without shifting the LED colour temperature, while analog dimming is simpler for constant-current control loops.
