R7731 Burst Triple Mode PWM Flyback Controller General Description The R7731 is a high performance, low cost, low start-up current, current mode PWM controller with burst triple mode to support green mode power saving operation.
The R7731 integrates functions of Soft-Start, Under Voltage 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 R7731 output driver is clamped at 12V.
Furthermore, R7731 features fruitful protec...
