OB2365A Datasheet Adaptive Multi-mode Pwm Controller

Manufacturer: On-Bright

Overview: OB2365A Adaptive Multi-Mode PWM Controller GENERAL.

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

General Description

OB2365A is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications.

At normal load condition, it operates in QR mode in high line input voltage.

To minimize switching loss, the maximum switching frequency in QR mode is internally limited to 77 KHz.

Key Features

  • Power on soft start reducing MOSFET Vds stress.
  • Multi-Mode Operation 77KHz maximum clamping frequency in QR mode @ Full Load in high line voltage 65KHz minimum clamping frequency in CCM mode @ Heavy Load in low line voltage Valley switching operation @ Green mode Burst Mode @ Light Load & No Load.
  • Frequency shuffling for EMI.
  • Extended burst mode control for improved efficiency and low standby power design.
  • Audio noise free operation.
  • Comprehensive protection covera.
