AP3156 Datasheet (Diodes) - HIGH EFFICIENCY 1X/1.5X/2X CHARGE PUMP

AP3156, HIGH EFFICIENCY 1X/1.5X/2X CHARGE PUMP

The AP3156 is a low noise, constant frequency charge pump DC/DC converter that uses a tri-mode load switch (1X), fractional (1.5X), and doubling (2X) conversion to maximize efficiency for white LED applications.

The AP3156 is capable of driving the LED channels at 120mA maximum from a 2.7V to 5.5V i
