ELM916DB is a high efficient LED driver control IC, which uses fewer components and drives LEDs with

constant current. ELM916DB works in constant frequency and the frequency can be programmed by an external

resistor. ELM916DB includes a high voltage regulator which makes it work in wide 10 to 600V input voltage

range without an external low voltage power supply. External 0 to 100% PWM dimming and 0 to 250mV linear

dimming help to adjust LEDs luminance. ELM916DB is suitable for buck, boost or buck-boost LED drivers.

It has a good stable response that is provided by open loop current mode control without any compensation

circuits.
