I would like to know about function of TZE. This pin is detected the voltage(or energy of transformer) at this pin.
(DS P.20 TRANSFORMER ZERO ENERGY DETECTION)
Does it mean this device is voltage control? Or power control mode?
Because our customer would like the voltage control mode.
And is it possible to achieve stable PFC operation at less than 10W (output power) at high Vin voltage?
The target power is ~60W. So that, our customer want PFC operation at as possible low power.
