OB2278 Datasheet Current Mode Pwm Controller

Manufacturer: On-Bright

Overview: Current Mode PWM ControllerLatch Shutdown OB2278 Product Specification.

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

General Description

OB2278 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

  • 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 selective protections for Latch Shutdown o VDD Over Voltage Protection(OVP).
  • Latch Shutdow.
