GENERAL DESCRIPTION
FEATURES
OB2513xC is a high performance offline PSR● Primary-side sensing and regulation without power switch for low power AC/DC charger and TL431 and opto-coupler adapter applications. It operates in primary-side
● High precision constant voltage and current sensing and regulation. Consequently, regulation at universal AC input opto-coupler and TL431 could be eliminated.
● Multi-mode PWM/PFM operation for efficiency Proprietary Constant Voltage (CV) and Constant improving Current (CC) control is integrated as shown in the
● Quasi-resonant operation for highest overall figure below. efficiency In CC control, the current and output power setting
● Programmable CV and CC regulation can be adjusted externally by the sense resistor
● Built-in line voltage and primary winding Rs at CS pin. In CV control, multi-mode operations inductance compensation are utilized to achieve high performance and high
● Programmable cable drop compensation efficiency. In addition, good load regulation is
● No need for control loop compensation achieved by the built-in cable drop compensation.
