MAX1912 Datasheet (Maxim) - 1.5x/2x High-Efficiency White LED Charge Pumps

MAX1912, 1.5x/2x High-Efficiency White LED Charge Pumps

The MAX1910/MAX1912 power LEDs with a regulated output voltage or current (up to 120mA) from an unregulated input supply (2.7V to 5.3V).

These are complete DC-DC converters requiring only four small ceramic capacitors and no inductors.

Input ripple is minimized by a unique regulation scheme that mai
