OB2283K Datasheet High Performance Current Mode Pwm Controller

Manufacturer: On-Bright

Overview: OB2283K High Performance Current Mode PWM Controller with peak load.

General Description

OB2283K 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.
  • Ultra Low Operating Current at Light Load (0.6mA).
  • Audio Noise Free Operation.
  • Normal 65KHz Switching Frequency.
  • Frequency Triple for peak load(195Khz).
  • Adjustable Overload Protection (OLP) delay time.
  • Comprehensive Protection Coverage o VCC Under Voltage Lockout with Hysteresis (UVLO) o Cy.
