OB2201 Datasheet High Performance Quasi-resonant Pwm Controller

Manufacturer: On-Bright

Overview: High Performance Quasi-Resonant PWM Controller OB2201 Product Specification.

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

General Description

OB2201 is a high performance flyback QuasiResonant (QR) controller optimized to achieve high efficiency in the universal input range and full loading range with effective system cost.

At full loading, the IC operates in fix frequency (52KHz) CCM mode in the low line input range and operates in QR mode in high line input range.

In this way, high efficiency in the universal input range at full loading can be achieved.

Key Features

  • protections against pin open and short conditions on selected pins. OB2201 is offered in SOP-8 and DIP-8 packages.
