ET5120/A数据手册ETEK中文资料规格书

描述 Description

 
The ET5120/A is a versatile constant current LED driver with a high efficiency DC-DC step up “boost”
converter architecture. Unique technology and high 880mA current limit allow ET5120/A to drive up to 37V output (10 LEDs in series).
Alternatively, ET5120/A can deliver 180mA total current with 3 series LEDs per string. It can also maximize the current capability while achieving high conversion efficiency. The optimized 0.9MHz switching frequencies result in small external component size. The driver allows a wide range of PWM dimming frequencies through the CTRL pin.
