OB25133
DESCRIPTION
FEATURES
OB2513x is a high performance offline PSR power
- Primary-side sensing and regulation without switch for low power AC/DC charger and adapter
TL431 and opto-coupler applications. It operates in primary-side sensing
- High precision constant voltage and current and regulation. Consequently, opto-coupler and TL431 could be eliminated. Proprietary Constant regulation at universal AC input
- Multi-mode PWM/PFM operation for efficiency
Voltage (CV) and Constant Current (CC) control is integrated as shown in the figure below. improving
- Good dynamic response
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
- Programmable CV and CC regulation
- Built-in line voltage and primary winding inductance pensation
- Programmable cable drop pensation efficiency. In addition, good load regulation is
- No need for...
