Description
The OB2273AP is a highly integrated current mode PWM control IC optimized for high performance, low standby power 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).
