Primary Feedback CC/CV PWM Controller

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. Primary Side CC/CV Control Current Mode Control Internal PWM Leading-Edge Blanking Green-Mode PWM Cycle-by-Cycle Current Limiting UVLO at 14V/8V OVP 27.5V on VDD Pin Brownout Protection Output Over Voltage Protection Built-in Jittering Frequency Soft Driving for EMI Programmable Cable Compensation Internal Over Temperature Protection Ordering Information R7710 Package Type E : SOT-23-6 Operating Temperature Range G : Green (Halogen Free with Comme- rcial Standard) Applications Switching AC/DC Adaptor and Battery Charger DVD Open Frame Power Supply STB Cell Phone Charger Networking Power Supply Note : Richpower Green products are : RoHS compliant and compatible with the current requirements of IPC/JEDEC J-STD-020.
