LM5025MTCX/NOPB
The LM5025 is an active-clamp forward PWM controller operating from high-voltage inputs up to 90 V, using voltage-mode control with feedforward and an 80% maximum duty cycle. It supports both N- and P-channel clamp FETs and includes current limiting, high-voltage startup, leading-edge blanking, soft start and thermal shutdown. It is used in isolated DC/DC and AC/DC power supplies.
