15A CMOS RF MOSFET Gate Driver

Categories: ,

The IXRFD615 is a low-side 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 minimum pulse widths.

The IXRFD615 can source and sink 15 Amperes of peak current while producing voltage rise and fall times of less than 5 nanoseconds and minimum pulse widths of 8 nanoseconds. The input of the driver is compatible with TTL or CMOS and is fully immune to latch-up over the entire operating range.

The IXRFD615 is packaged in a low-inductance surface mount RF package incorporating advanced layout techniques to minimize stray lead inductances for optimum switching performance.

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 performance and value.
