OB3390/1/T

Low Cost PSR Control LED Lighting Driver (For BJT)

OB3390 is a primary side control offline LED lighting which can achieve accurate LED current and low system cost for an isolate lighting application in a single stage converter. It can significantly simplify the LED lighting system design by eliminating the secondary side feedback components and the optocoupler.


Features:

◆High precision Constant Current Regulation at Universal AC input
◆Primary-side Sensing and Regulation Without TL431 and Opto-coupler
◆Low System Cost and High Efficiency
◆Programmable CC Regulation
◆Built-in Primary winding inductance compensation
◆Driver BJT Switch
◆Ultra Low Start-up Current (T*. 1uA)
◆LED short Protection
◆LED open Protection
◆Cycle-by-Cycle Current Limiting
◆Built-in Leading Edge Blanking (LEB)
◆VDD Over Voltage Protection
◆VDD Under Voltage Lockout with Hysteresis
◆Available in SOT23-5 packages, RoHS compliant

Applications:

◆LED Lighting
◆LED PAR Lamp
