OB2276 Datasheet High Performance Current Mode Pwm Controller

Manufacturer: On-Bright

Overview: OB2276 High Performance Current Mode PWM Controller GENERAL.

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

General Description

OB2276 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 internally fixed and is 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 Reducing MOSFET Vds Stress.
  • Frequency shuffling for EMI.
  • Extended Burst Mode Control For Improved Efficiency and Minimum Standby Power Design.
  • Audio Noise Free Operation.
  • Fixed 65KHZ Switching Frequency.
  • Comprehensive Protection Coverage o VDD Under Voltage Lockout with Hysteresis (UVLO) o Cycle-by-cycle over current threshold setting for constant output power limiting over universal input voltage range o Overload Protection (OLP) with autorecov.
