Overview
OB2513x is a high performance offline PSR power switch for low power AC/DC charger and adapter applications. It operates in primary- side sensing and regulation. Consequently, opto- coupler and TL431 could be eliminated. Proprietary Constant Voltage (CV) and Constant Current (CC) control is integrated. In CC control, the current and output power setting can be adjusted externally by the sense resistor Rs at CS pin. In CV control, multi- mode operations are utilized to achieve high performance and high efficiency. In addition, good load regulation is achieved by the built- in cable drop compensation. Device operates in PFM in CC mode as well at large load condition and it operates in PwM with frequency reduction at light/medium load. The chip consumes very low operation current, it can achieve less than 75mW standby power. OB2513x offers 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. OB2513x is offered in SOP7 package.
