Introduction

AI Translation

OB2513x is a cost effective PSR power switch optimized for off-line low power AC/DC applications including battery chargers. It operates in primary side sensing and regulation, thus opto-coupler and TL431 are not required. Proprietary built-in CV and CC control can achieve high precision CC/CV control meeting most charger application requirements.

Features

AI Translation
  • High performance offline PSR power switch
  • Operates in primary-side sensing and regulation, eliminating opto-coupler and TL431
  • Proprietary Constant Voltage (CV) and Constant Current (CC) control integrated
  • Current and output power setting adjustable externally by sense resistor Rs at CS pin in CC control
  • Multi-mode operations utilized in CV control for high performance and high efficiency
  • Built-in cable drop compensation for good load regulation
  • Operates in PFM in CC mode and at large load condition, operates in PWM with frequency reduction at light/medium load
  • Very low operation current, can achieve less than 75mW standby power
  • Comprehensive protection coverage with auto-recovery features including Cycle-by-Cycle current limiting, VDD over voltage protection, short circuit protection, built-in leading edge blanking, VDD under voltage lockout (UVLO), OTP etc.
  • Offered in SOP7 package

Applications

AI Translation
  • Low Power AC/DC offline SMPS for Cell Phone Charger
  • Digital Cameras Charger
  • Small Power Adapter
  • Auxiliary Power for PC, TV etc.
  • Linear Regulator/RCC Replacement
