Datasheet Summary
High Efficiency 1×/1.5× Charge Pump 4-Channels LED Driver
DESCRIPTION
BL8588 is a low noise, high efficiency, and constant frequency charge pump DC/DC converter for white LED application. The operation frequency is 1MHz.
BL8588 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 1µF and two 0.47µF capacitors are required to build a pact and low-cost power supply solution.
BL8588 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...
