Optocoupled Feedback
Isolated voltage feedback is achieved by using an opto-
coupler and a shunt regulator as shown in Figure 2. The
output voltage set point accuracy is a function of the
accuracy of the shunt regulator and feedback resistor-
divider tolerance.
Internal Regulators
The internal regulators of the MAX5014/MAX5015
enable initial startup without a lossy startup resistor and
regulate the voltage at the output of a tertiary (bias)
winding to provide power for the IC. At startup V+ is
regulated down to V CC to provide bias for the device.
The V DD regulator then regulates from the output of the
tertiary winding to V CC . This architecture allows the ter-
tiary winding to only have a small filter capacitor at its
output thus eliminating the additional cost of a filter
inductor.
When designing the tertiary winding calculate the num-
ber of turns so the minimum reflected voltage is always
higher than 12.7V. The maximum reflected voltage
must be less than 36V.
