... MOSFET’s gate capacitance during high-to-low signal transitions. When the power MOSFET’s gate is pulled high by the LTC1693-5, its drain voltage is pulled low by its load (e.g., a resistor or inductor). The slew rate of the drain voltage causes current to flow back to the MOSFETs gate through its gate-to-drain capacitance ...

... Input Voltage Range LTC1693-5’s input pin is a high impedance node and essentially draws neligible input current. This simplifies the input drive circuitry required for the input. The LTC1693-5 typically has 1.2V of hysteresis between its low and high input thresholds. This increases the driver’ ...
