DC2708A: LTC7001 Fast High Voltage High Side NMOS Static Switch Driver
Demonstration circuit DC2708A is a 135V, 5A high-side switch featuring the LTC7001 NMOS driver, providing fast switching times and 100% duty cycle operation.
Overview
The DC2708A is a demonstration board for the LTC7001, a fast high-voltage N-channel MOSFET driver. The circuit is designed to switch a 5A output load from 0V up to 135V. It features a typical propagation delay of 50ns, fast switching times under 10ns, and 100% duty cycle capability enabled by an internal charge pump. The document provides a performance summary, setup procedures, a complete bill of materials, and detailed schematic diagrams. It utilizes the Fairchild FDMS86250 MOSFET and supports VCC supply ranges from 7V to 12V.
