ET5119数据手册ETEK中文资料规格书

描述 Description

The ET5119A/B/C is an asynchronous constant-current LED driver capable of efficiently driving a string of up to ten LEDs in series. The high fixed switching frequency allows the use of small chip inductors and capacitors. \r
The ET5119A/B/C uses a simple single-wire digital control interface to program the brightness levels of the LEDs in 32 linear steps by applying digital pulses.\r
The feedback voltage of ET5119A/B/C is 0.2V used for LED driver. \r
For safety, The ET5119A/B/C features integrated over-voltage, over-current, thermal-shutdown protection, and input under-voltage lockout.
