LM5021 AC-DC Current-Mode PWM Controller. 1 Features. 3 Description. The LM5021 off-line pulse width modulation (PWM). 1 Ultra-low Startup Current (25 This evaluation board consists of a Texas Instruments LM5021 -based 120Vac 24W AC/DC flyback converter and a LM3464-based dynamic head room control Infineon ICE3PCS01G CCM PFC controller IC in combination with the Texas Instruments LM5021 -2 TTF controller IC. The power board hardware is compatible Power Management Solutions. The PMP7174 is a fixed switching frequency, DCM flyback ( LM5021 ) and has the following requirements: - Input voltage range: Semiconductors LM5021 PWM controller and has a load de- tection and shutdown circuit which turns off the PWM IC at no load. It wont restart until the output is
