AP3156  
HIGH EFFICIENCY 1X/1.5X/2X CHARGE PUMP  
FOR WHITE LED APPLICATIONS  
General Description  
Features  
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 input. The  
current sinks may be operated individually or in parallel for driving  
higher-current LEDs. A low external parts count (two 1µF flying  
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  
capacitors and two small 1µF capacitors at VIN and VOUT) make  
this part ideally suited for small, battery-powered applications.  
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 Application Circuit  
Built-In Thermal Protection  
Built-In Auto-Disable For Open Circuit  
Automatic Soft Start  
AP3156 serial digital input is used to enable, disable and set  
current for each LED with a 32-level logarithmic scale plus four  
low-current settings down to 50µA for optimized efficiency, with a  
low quiescent current of only 50µA.  
Each output of the AP3156 is equipped with built-in protection for  
VOUT short circuit and auto-disable for LED failure conditions.  
Built-in soft-start circuitry prevents excessive inrush current  
during start-up. A low-current shutdown feature disconnects the  
load from VIN and reduces quiescent current to less than 1µA.  
IQ <1µA in Shutdown  
Thermally-Enhanced QFN4040-16 Package: Available  
in “Green” Molding Compound (No Br, Sb)  
The AP3156 is available in a lead-free, space-saving, thermally  
enhanced 16-pin 4x4mm QFN package.  
Lead Free Finish / RoHS Compliant (Note 1)
