OB2500N Datasheet High Precision Cc/cv Primary-side Power Switch

Manufacturer: On-Bright

Overview: OB2500N High Precision CC/CV Primary-Side Power Switch GENERAL.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

OB2500N is a high performance offline PSR power switch 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

  • Primary-side sensing and regulation without TL431 and opto-coupler.
  • High precision constant voltage and current regulation at universal AC input.
  • Multi-mode PWM/PFM operation for efficiency improving.
  • Integrated 1A 650V MOSFET.
  • Good dynamic response.
  • Programmable CV and CC regulation.
  • Built-in primary winding inductance compensation.
  • Programmable cable drop compensation.
  • No need for control loop compensation.
  • Audio noise free operation.
  • Bui.
