Overview
EUP3651 4-Channel, 1X/1.
5X Charge Pump White LED Driver DESCRIPTION The EUP3651 is a high efficiency charge pump white LED driver.
It supports 4 white LEDs with regulated constant current for uniform intensity.
The EUP3651 maintains the highest efficiency by utilizing a 1.
5X fractional charge pump and low dropout current regulators.
A low external parts count (two 1uF flying capacitors and two small 1uF capacitors at VIN and VOUT) makes the EUP3651 ideally suited for small battery-powered applications.
The EN logic input is used to enable, disable, and set current with a 16-step linear scale.
The LED current can be configured between 5mA and 25mA.
If EN is kept low for more than 1.
5ms, the EU...
