OB3394 is a primary side regulation off-line LED lighting controller which can achieve accurate LED current. It significantly simplifies LED lighting system design by eliminating the secondary side feedback circuitry.
Features:
◆ High Precise Constant Current Regulation at Universal AC input
◆ Primary-side Sensing and Regulation Without TL431 and Opto-coupler
◆ Programmable CC Regulation
◆ Adjustable Constant Current and Output Power Setting
◆ Built-in Secondary Constant Current Control with Primary Side Feedback
◆ Built-in Adaptive Current Peak Regulation
◆ Built-in Primary winding inductance compensation
◆ Power on Soft-start
◆ Cycle-by-Cycle Current Limiting
◆ Built-in Leading Edge Blanking (LEB)
◆ VDD Under Voltage Lockout with Hysteresis (UVLO)
◆ VDD OVP
◆ VDD Clamp
◆ Available in DIP8 packages, RoHS compliant
Applications:
Low Power AC/DC offline SMPS for
◆ LED applications
