OB2305
DESCRIPTION
FEATURES
OB2305 is a high performance offline PSR
- Primary-side sensing and regulation without controller 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
- Less than 30m W standby power consumption figure below. at 230V with typical application circuit
In CC control, the current and output power setting
- Programmable CV and CC regulation can be adjusted externally by the sense resistor
- Built-in dynamic signal detection from 2nd-side
Rs at CS pin. In CV control, multi-mode operations synchronous rectification are utilized to achieve high performance and high
- Built-in line voltage and...
