Analog Devices Flyback Controllers: Can the LT8316 handle an input voltage of 900V (rated)?

power management

The input voltage is 900V, but it can be applied if the input stage is devised. As described in P20 "Expansion of power supply voltage range" of the datasheet, using a 600V Zener diode allows up to 1200V input.

For an actual application example, please refer to "Extending the power supply voltage of a 600V input isolated flyback controller that does not require an optocoupler to 800V or higher".
