110-V active clamp current mode PWM controller, featuring a P-channel clamp FET and 0.75V CS threshold, operates with a 12V supply voltage (8.5V to 14.5V range) and delivers 2A output current. This integrated circuit offers a 250kHz frequency with a 73% duty cycle, expandable up to 1MHz and 74% duty cycle respectively. Packaged in a 16-SOIC (D) case, it functions across a -40°C to 85°C temperature range. RoHS compliant and lead-free, this flyback topology controller is supplied in rail/tube packaging.
