The DEIC420 is a CMOS high speed high current gate driver specifically designed to drive MOSFETs in Class D and E HF RF applications at up to 45MHz, as well as other applications requiring ultrafast rise and fall times or short minimum pulse widths.
The DEIC420 is a CMOS high‑speed, high‑current gate driver designed for driving MOSFETs in Class D and E RF applications up to 45 MHz. It delivers up to 20 A peak output current, rise and fall times under 4 ns, and a minimum pulse width of 8 ns, while supporting TTL or CMOS input levels.
Typical applications include RF MOSFET drivers, Class D/E switching amplifiers, high‑frequency SMPS, pulse generators, acoustic transducer drivers, pulsed laser diode drivers, DC‑DC converters, and pulse‑transformer drivers. The device is offered in a low‑inductance RF package and a 28‑pin SOIC version for lower‑power needs.
| Peak Output Current | 20 A |
|---|---|
