Analog Devices Flyback Controller: How should I choose the resistor RVCC between VIN and VCC for the LTC3805?

power management

The LTC3805 has an internal shunt regulator from VCC to GND that limits the voltage to less than 9.5V. Set RVCC so that the internal shunt regulator draws less than 25mA.
