OB2520 is a high performance offline PSR controller 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.
Features:
◆ Ultra Low Standby Power
◆ ±5% Constant Voltage Regulation at Universal AC input
◆ High precision Constant Current Regulation at Universal AC input
◆ Primary-side Sensing and Regulation Without TL431 and Opto-coupler
◆ Programmable CV and CC Regulation
◆ Built-in Primary winding inductance compensation
◆ Programmable Cable Drop Compensation
◆ Driver BJT Switch
◆ Ultra Low Start-up Current (Typ. 1uA)
◆ VDD Over Voltage Protection
◆ Built-in Feedback Loop Open Protection
◆ Built-in Short Circuit Protection
◆ Built-in Leading Edge Blanking (LEB)
◆ Cycle-by-Cycle Current Limiting
◆ VDD Under Voltage Lockout with Hysteresis (UVLO)
◆ Available in SOT23-6 package, RoHS compliant
Applications:
◆ Cell Phone Charger
◆ PMP Adapter/Charger
◆ Small Power Adapter
◆ Auxiliary Power for PC, TV etc.
◆ Linear Regulator/RCC Replacement
