... D1 U OPERATIO (Refer to Functional Diagram) The LT1160 (or 1/2 LT1162) incorporates two indepen- dent driver channels with separate inputs and outputs. The inputs are TTL/CMOS compatible; they can withstand + input voltages as high The 1.4V input threshold is regulated and has 300mV of hysteresis. Both channels are noninverting drivers ...

... U U APPLICATIONS INFORMATION Power MOSFET Selection Since the LT1160 (or 1/2 LT1162) inherently protects the top and bottom MOSFETs from simultaneous conduction, there are no size or matching constraints. Therefore selec- tion can be made based on the operating voltage and R requirements. The MOSFET BV DS(ON) greater than the HV and should be increased to approxi- mately (2)(HV) in harsh environments with frequent fault conditions ...

... MOSFET do not cause any problems. Switching Regulator Applications The LT1160 (or 1/2 LT1162) is ideal as a synchronous switch driver to improve the efficiency of step-down (buck) switching regulators. Most step-down regulators use a high current Schottky diode to conduct the inductor current when the switch is off ...
