RT7730
RT7730 is Burst Triple-mode PWM Flyback Controller manufactured by Richtek.
Preliminary
Burst Triple-mode PWM Flyback Controller
General Description
The RT7730 is a high-performance, low cost, low startup current, current mode PWM controller with burst triplemode to support green mode power saving operation. The RT7730 integrates functions of Soft Start, Under VoItage Lockout (UVLO), Leading Edge Blanking (LEB), Over Temperature Protuction (OTP), internal slope pensation. It provides the users a superior AC/DC power application of higher efficiency, low external ponent counts and lower cost solution.
To protect the external power MOSFET from being damaged by supply over voltage, the RT7730 output driver is clamped at 13.5V. Furthermore, RT7730...
