OB2287 - High Performance Current Mode PWM Controller

Download the OB2287 datasheet PDF. This datasheet also covers the OB2287-On variant, as both devices belong to the same high performance current mode pwm controller family and are provided as variant models within a single manufacturer datasheet.

Description

OB2287 is a highly integrated current mode PWM controller for medium to large power offline flyback converter applications.

OB2287 enhances On-Bright’s PWM controller series by offering the Brownout Detection and Protection (BOP).

Features

  • protections against pin open and short on selected pins. On-Bright’s proprietary OCP compensation can compensate CCM and DCM mode difference when used in universal AC input.
