Introduction

AI Translation

OB3399 is a cost effective PWM controller optimized for off-line LED lighting applications. Based on flyback converter topology working in DCM mode, It operates in primary side sensing and regulation, thus opto-coupler and TL431 are not required. Proprietary built-in CC control can achieve high precision LED current meeting LED lighting application requirements.

Features

AI Translation
  • High Precise Constant Current Regulation at Universal AC input
  • Primary-side Sensing and Regulation Without TL431 and Opto-coupler
  • Adjustable Constant Current and Output Power Setting
  • Adjustable Constant Voltage Load Compensation
  • Built-in Primary Winding Inductance Compensation
  • Built-in Leading Edge Blanking (LEB)
  • Cycle-by-Cycle Current Limiting
  • VDD Under Voltage Lockout with Hysteresis (UVLO)
  • Latched over temperature protection (OTP)
  • VDD Clamp
