The circuit operates with inputs up to 52 V, with a power-saving feature that turns off driver current once the external FET has been turned on fully. This feature extends the flexibility of the device, allowing it to operate with an input voltage up to 52 V without dissipating excessive power. The circuit operates with voltage-mode feedback and has feedforward input-voltage ...
