OB2263 Datasheet Current Mode Pwm Controller

Manufacturer: On-Bright

Overview: OB2263 Current Mode PWM ControllerFrequency Shuffling GENERAL.

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

General Description

OB2263 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications in sub 30W range.

PWM switching frequency at normal operation is externally programmable and trimmed to tight range.

At no load or light load condition, the IC operates in extended ‘burst mode’ to minimize switching loss.

Key Features

  • On-Bright Proprietary Frequency Shuffling Technology for Improved EMI Performance.
  • Extended Burst Mode Control For Improved Efficiency and Minimum Standby Power Design.
  • Audio Noise Free Operation.
  • External Programmable PWM Switching Frequency.
  • Internal Synchronized Slope Compensation.
  • Low VDD Startup Current and Low Operating Current (1.4mA).
  • Leading Edge Blanking on Current Sense Input.
  • Good Protection Coverage With Auto Self- Recovery o VDD Over Voltag.
