Preliminary
R7710
Primary Feedback CC/CV PWM Controller for Flyback Converters
General Description
Features
The R7710 is a current mode PWM controller which includes primary side voltage feedback technology. It controls the output voltage and current accurately without shunt regulator and photo coupler on secondary side to save the part counts and cost.
R7710 is designed especially for low power purpose as charger of cell phones, PDAs..., and etc. Fruitful protections, such as UVP, OVP, brownout, current limit and OTP, minimize the external components. Ultra low start-up current and operating current of R7710 achieves the low power consumption in standby mode. The green mode operation of R7710 also meets the latest efficiency regulations.
