    Preliminary R7914 Enhanced Burst Triple-Mode PWM Controller with Integrated Power MOSFET for Flyback Converts General Description Features The R7914 series consists of a high voltage power MOSFET and a high-performance, low cost, low start-up current and current mode PWM controller with burst triplemode to support green mode power saving operation. The R7914 integrates functions of soft start, Under VoItage LockOut (UVLO), Leading Edge Blanking (LEB), Over Temperature Protection (OTP) and internal slope compensation. It provides the users a superior AC/DC power application of higher efficiency, low external component counts and lower cost solution. To protect the internal power MOSFET from being damaged by supply over voltage, the R7914 driver is clamped at 12V.
