High Efficiency 1x/1.5x Charge Pump 4-Channels LED Driver |
LC3606 is a low noise, high efficiency, and constant frequency charge pump DC/DC converter for white LED application. The operation frequency is 1MHz. LC3606 works in load switch (1´) and fractional (1.5´) modes with four independent control outputs, each channel can provide 20mA constant current precisely from a 2.8V to 5.5V supply. Only two external 1uF and two 0.47uF capacitors are required to build a compact and low-cost power supply solution. LC3606 uses EN pin for simple on/off control and single wire serial pulse dimming in 16 steps. A low current shutdown feature disconnects the load from VIN and reduces quiescent current to less than 1µA. |
