OB2510 - High Precision CC/CV Primary-Side Controller

Download the OB2510 datasheet PDF. This datasheet also covers the OB2510-On variant, as both devices belong to the same high precision cc/cv primary-side controller family and are provided as variant models within a single manufacturer datasheet.

General Description

OB2510 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.

Key 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. OB2510 is offered in SOT23-5 package.

OB2510 High Precision CC/CV Primary-Side Controller GENERAL DESCRIPTION OB2510 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. 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.
