AC-DC buck LED driver circuit

The ET2126 is a low noise, constant frequency charge pump DC/DC converter for white LED applications. The ET2126 is capable of driving up to four channels of LEDs at preset 20mA per channel from a 2.5V to 6.0V input. The current sinks may be operated individually parallel for driving higher current • VIN Range: 2.5V to 6.0V\r\n• Fully Programmable Current with Single Wire——16 Current Levels\r\n• Drives up to Four Channels of LEDs\r\n• Overcurrent and Overtemperature Protected\r\n• No Inductors, Low Noise Operation\r\n• Small Application Circuit\r\n• Automatic Soft Start\r\n• I Q <1μA in Shutdo;
