OB2276 Product details

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.

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.
