General Description
The MAX8819_ is a complete power solution for MP3 players and other handheld applications.

The IC includes a battery charger, step-down converters, and WLED power. It features an input current-limit switch to power the IC from an AC-to-DC adapter or USB port, a 1-cell lithium ion (Li+) or lithium polymer (Li-Poly) charger, three step-down converters, and a step-up converter with serial step dimming for powering two to six white LEDs. All power switches for charging and switching the system load between battery and external power are included on-chip. No external MOSFETs are required. The MAX8819C/MAX8819D offer a sequenced powerup/power-down of OUT1, OUT2, and then OUT3. Maxim's Smart Power SelectorTM makes the best use of AC-to-DC adapter power or limited USB power. Battery charge current and input current limit are independently set. Input pow
