R7731A
Burst Triple Mode PWM Flyback Controller
General Description
The R7731A is a high-performance, low cost, low start-up current and current mode PWM controller with burst triple mode to support green mode power saving operation.
The R7731A integrates functions of soft start, Under
Voltage 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 external power
MOSFET from being damaged by supply over
voltage, the R7731A output driver is clamped at 12V.
Furthermore, R7731A features frui...
