GENERAL DESCRIPTION
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 as shown in the figure below.
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
