Preliminary R7730 Burst Triple-Mode PWM Flyback Controller General Description The R7730 is a high-performance, low cost, low startup current, current mode PWM controller with burst triplemode to support green mode power saving operation. The R7730 integrates functions of soft-start, Under VoItage Lockout (UVLO), Leading Edge Blanking (LEB), Over Temperature Protection (OTP), 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 external power MOSFET from being damaged by supply over voltage, the R7730 output driver is clamped at 12V.
