MOSFET Drivers suit power supply applications over 500 kHz.May 5, 2006 -
Consisting of tiny single drivers for inverting and non-inverting solutions, Series MIC44F18/19/20 targets power supplies and synchronous rectification applications operating at frequencies up to 2 MHz. Output voltage levels can swing within 25 mV of positive supply ground. With input voltage of 4.5-13.2 V, chips are capable of symmetrically sinking and sourcing current up to 6 A with propagation delay of 10 ns and switching times of 15 ns.

Micrel Launches Industry's Smallest Ultra High Speed, 6A MOSFET Driver Product Family
New 6A High Speed Drivers Ideal for Over 500kHz Tiny Power Supply Solutions
SAN JOSE, Calif., April 4 /-- Micrel Inc. (NASDAQ:MCRL), the industry leader in analog, high bandwidth communications and Ethernet IC solutions, today launched a new line of tiny, high speed MOSFET drivers. The MIC44F18/19/20 MOSFET driver family is a series of new 6A devices targeted at power supplies and synchronous rectification applications operating at frequencies as fast as 2MHz. The ICs are available in volume with pricing starting at $0.75 for 10K quantities.
The MIC44F18/19/20 MOSFET drivers are tiny single drivers for inverting and non-inverting solutions. They are fabricated with Micrel's proprietary BiCMOS/DMOS process for low power consumption and high efficiency TTL and CMOS input logic level compliance. Output voltage levels can swing within 25mV of the positive supply ground, in comparison to bipolar devices, which are only capable of swinging within 1V of the supply. These chips are capable of symmetrically sinking and sourcing current up to 6A with an industry breakthrough propagation delay of 10ns and switching times of 15ns.
"As designers continue to push for more efficient solutions and higher power densities, Micrel demonstrates yet again its ability to deliver high-performance, state-of-the-art devices for the industry's most demanding power designs," noted Ralf Muenster, Micrel's director of marketing for power products. "The MIC44F MOSFET driver series provides solutions for extreme power density requirements with the smallest possible package size, a tiny 2 x 2 MLF(TM) and is suitable for high switching frequencies up to 2MHz."
The MIC44F18/19/20 series feature an input voltage range from 4.5 to 13.2V, ideal for a wide range of power applications with 5V and regulated 12V voltage buses. The solutions also include enable function, latch-up protection, and programmable UVLO functions. They are offered in thermally enhanced packages, an exposed Pad MSOP-8 and 2 x 2 mm MLF(TM)-8 package options.
