Advanced PWM controller for half-bridge and full-bridge topologies, featuring pre-bias operation for offline applications. This surface mount integrated circuit offers a maximum operating frequency of 945kHz and a 100% maximum duty cycle. It operates from a 12V supply voltage, with a maximum of 17V, and provides two positive PWM outputs. The component is housed in a 20-TSSOP package, supports synchronous rectification, and operates across a temperature range of -40°C to 125°C.
