OB2578T Product details

Description

OB2578T is an excellent primary side regulation power switch with CC/CV operation for medium level power AC/DC charger and adapter applications.

The device operates in CCM/QR mode to provide high efficiency along with several functions of built-in protections.

Features

Primary-side sensing and regulation operates in CCM/QR mode without TL431 and opto-coupler.
High precision constant voltage and current regulation at universal AC input.
Fixed frequency (65kHz) CCM mode operation with low line voltage at full load.
Integrated 4A MOSFET.
Quasi-resonant operation for high efficiency in high line voltage.
Programmable CV and CC regulation.
Good dynamic response.
Built-in line compensation for tight CC regulation.
Built-.
