Overview
BL8587
High Efficiency 1×/1.
5× Charge Pump 4-Channels LED Driver
DESCRIPTION
BL8587 is a low noise, high efficiency, and constant frequency charge pump DC/DC converter for white LED application.
The operation frequency is 1MHz.
BL8587 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 compact and low-cost power supply solution.
BL8587 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 q...
