... The ground pins should not be tied together if isolation is required between the two drivers of the LTC1693-1 and the LTC1693-2. OUT 1, OUT2 (Pins 5, 7): Driver Outputs. The LTC1693- 1’s outputs are in phase with their respective inputs (IN1, IN2). The LTC1693-2’s topside driver output (OUT1 phase with its input (IN1) and the bottom side driver’ ...

... MOSFET’s gate capacitance during high-to-low signal transitions. When the power MOSFET’s gate is pulled low by the LTC1693, its drain voltage is pulled high 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 ...

... Different Ground Potentials W U driver is powered with respect to ground. Similarly Figure 3 shows a simplified circuit of a LTC1693-1 which is driv- ing MOSFETs with different ground potentials. Because there isolation between these drivers in a single package, ground current on the secondary side will not recirculate to the primary side of the circuit ...

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