OB2576TCP Datasheet High Performance Qr Mode Primary-side Power Switch

Manufacturer: On-Bright

Overview: OB2576xT High Performance QR mode Primary-Side Power Switch GENERAL.

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

General Description

OB2576xT is an excellent primary side regulation power switch with CC/CV operation for medium level power AC/DC charger and adapter applications.

The device integrates an internal power MOSFET and operates in QR mode to provide high efficiency along with several functions of built-in protections.

It removes the need for secondary feedback circuitry to lower the total bill of material cost.

Key Features

  • Primary-side sensing and regulation operates in QR mode without TL431 and opto-coupler.
  • High precision constant voltage and current regulation at universal AC input.
  • Programmable CV and CC regulation.
  • Integrated power MOSFET.
  • Good dynamic response.
  • Built-in line compensation for tight CC regulation.
  • Built-in fixed cable compensation.
  • Built-in primary winding inductance compensation.
  • Built-in control loop compensation.
  • Built-in leading edge blank.
