OB2273 Series
High Performance Current Mode PWM Controller
OB2273 is a highly integrated current mode PWM control IC optimized for high performance, low standby
power(less than 100mW) and cost effective offline flyback converter applications. It offers complete
protection coverage with auto-recovery including Cycle-by-Cycle current limiting (OCP), over load protection (OLP), and VDD under voltage lockout (UVLO). It also
provides the protections with latched shut down including over temperature protection (OTP), and over
voltage (fixed or adjustable) protection (OVP).
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

OB522X Series
High Voltage Green Mode Power Switch
OB5222 is a highly integrated current mode PWM Power Switch with high voltage start up, optimized for
high performance, low standby power consumption and cost effective offline flyback converter
applications.PWM switching frequency at normal operation is internally fixed . At no load or light load
condition, the IC operates in extended ‘burst mode’ to minimize switching loss. Very low standby
power consumption and very high conversion efficiency is thus achieved. Excellent EMI performance
is achieved with On-Bright proprietary frequency shuffling technique.
