450V LED controller

ELM916DA

■General description

ELM916DA is high efﬁciency LED driver control IC, which uses fewer components and drives LED with

constant current. ELM916DA works in open loop and current mode, and can be programmed to operate in either

constant frequency or constant off-time mode. ELM916DA consists of an 8 to 450V linear regulator, which

makes working in wide input voltage range without external low voltage power supply Internal 0 to 100%

PWM dimming and 0 to 245mV linear dimming help to adjust LED luminance. ELM916DA is suitable for buck

LED drivers; it is capable of providing good stability response because of open loop current mode control and

with the controller, it is able to regulate output current without any compensation outstandingly.
