Description

The IXRFD615 is a CMOS high

-speed, high-current gate driver

specifically designed to drive

MOSFETs in Class D and E HF

RF applications as well as other

applications requiring ultrafast

rise and fall times or short mini-

mum pulse widths. The

IXRFD615 can source and sink 15 A of peak current

while producing voltage rise and fall times of less than

5 ns and minimum pulse widths of 8 ns. The input of

the driver is compatible with TTL or CMOS and is fully

immune to latch up over the entire operating range.

Designed with small internal delays, cross conduction

or current shoot-through is virtually eliminated. The

features and wide safety margin in operating voltage

and power make the IXRFD615 unmatched in perfor-

mance and value.

The surface mount IXRFD615 is packaged in a low-

inductance RF package incorporating advanced layout

techniques to minimize stray lead inductances for opti-

mum switching performance.
