DC2750A: 14.5A @ 60V, High-Side N-Ch MOSFET Driver

Summary

Demonstration circuit 2750A is a 60V, high side switch featuring the LTC®7004. This demo board is designed to switch a 14.5A output load from 0V up to 60V, and offers a low 50ns (typical) propagation delay, fast switching times (<10ns) and 100% duty cycle operation.

The LTC7004 is a fast high side N-channel MOSFET driver. An internal charge pump fully enhances an external N-channel MOSFET switch, allowing it to remain on indefinitely. A powerful gate driver can drive large gate capacitance MOSFETs with very short transition times, ideal for both high frequency switching and static switch applications. The LTC7004 operates over a 0V to 60V input supply range.

The demo board includes input capacitors and an output diode to accommodate input and output supply inductance when switching loads. The switch can be controlled by providing an external signal on INPUT turret. The VCC input must be powered with an external power supply to provide power to the controller. Positions for RC delay network to control inrush current are also included.

The LTC7004 data sheet gives a complete description of the part, operation and application information. The data sheet must be read in conjunction with this DC2750A demo manual. Proper board layout is essential for maximum thermal and electrical performance.
