MAX8645Y 1x/1.5x/2x White LED Charge Pumps

The MAX8645X/MAX8645Y charge pumps drive up to eight white LEDs with regulated constant current for uniform intensity. The main group of LEDs (M1 *M6) can be driven up to 30mA per LED for backlighting. The flash group of LEDs (F1 and F2) is independently controlled and can be driven up to 200.

MAX8645Y Features

* Power Up to Eight LEDs Up to 30mA/LED Drive for Backlight Up to 400mA Total Drive for Flash

* Two Internal Low-Noise 200mA LDOs

* 94% Max/85% Avg Efficiency (PLED/PBATT) over Li+ Battery Discharge

* 0.2% Typical LED Current Matching

* Adaptive 1x/1.5x/2x Mod
