Product details

Description

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.

Features

VIN Range: 2.7V to 5.5V Fully Programmable Current with Single Wire.
32-Step Logarithmic Scale.
20/25mA Max Current per Channel.
Four Low Current Settings Down to 50µA.
Low IQ (50µA) for Low Current Mode Tri-Mode 1X, 1.5X, and 2X Charge Pump for Maximum Efficiency and VF Coverage Drives up to Six Channels of LEDs Individual Main/Sub-Group Control No Inductors, Low Noise Operation 0.5/1/2MHz Constant Switching Frequency Small.
