Advanced half-bridge/full-bridge PWM controller for offline applications, featuring a 100% maximum duty cycle and 945kHz operating frequency. This surface mountable, lead-free integrated circuit offers synchronous rectification and a push-pull topology. It operates from a 4.7V to 17V supply voltage, with a typical supply current of 2mA and a maximum of 275uA. The controller provides two positive outputs with a 3.25V output voltage and 200mA output current, and a fall time of 8ns. Packaged in a 4.15mm x 4.15mm x 0.95mm QFN, it is RoHS compliant and suitable for operation between -40°C and 125°C.
