... The primary-side PWM integrated Power MOSFET, FSEZ1216, significantly simplifies power supply design that requires CV and CC regulation capabilities. FSEZ1216 controls the output voltage and current precisely only with the information in the primary side of the power supply, not only removing the output current sensing loss, but also eliminating all secondary feedback circuitry ...
