OB2500N Product details

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.

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.
