产品介绍

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
◆ Comprehensive Protection Coverage
◇ VDD Under Voltage Lockout with Hysteresis (UVLO)
◇ Cycle-by-cycle over current threshold setting for constant output
