OB2535 Series

High Precision CC/CV PSR PWM Controller/Power Switch

OB2535 is a high performance offline PWM Power switch for low power AC/DC charger and adapter applications. It can achieve ±5% precision constant voltage (CV) and high precision constant current (CC). It operates in primary-side sensing and regulation. Consequently, opto-coupler and TL431 could be eliminated.

Features:

◆ ±5% constant voltage regulation at universal AC input
◆ Primary-side sensing and regulation without TL431 and opto-coupler
◆ Programmable CV and CC regulation
◆ Adjustable constant current and output power setting
◆ Built-in primary winding inductance compensation
◆ Programmable cable drop compensation
◆ Power on soft-start
◆ Built-in leading edge blanking (LEB)
◆ Cycle-by-Cycle current limiting
◆ VDD under voltage lockout with hysteresis (UVLO)
◆ VDD OVP
◆ VDD clamp
◆ Available in SOP8 packages, RoHS compliant

Applications:

◆ CC/CV Battery Charger
◇ Cell/Cordless Phone Charger
◇ Digital Camera Charger
◇ PDA Charger
◆ Small Power Adapter
◆ Auxiliary Power for PC, TV etc.
◆ Linear Regulator/RCC Replacement
