OB2279 Datasheet Current Mode Pwm Controller

Manufacturer: On-Bright

Overview: RESLEEPRAILSCEAELAODSNNEFTIO:oDD2EOA7NP9NT0IDO0AT6L8COPY OB2279 Current Mode PWM ControllerFreq Shuffling with Latch Shutdown.

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

General Description

OB2279 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications.

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.
  • Power On Soft Start.
  • 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 VIN/VDD Startup Current(3uA) and Low Operating Current (2.3mA).
  • Leading Edge Blanking on Current Sense Input.
  • Complete Protection Coverage with.
