Description
The DrMOS family is Fairchild’s next-generation, fully
optimized, ultra-compact, integrated MOSFET-plus-
driver, power-stage solution for high-current, high-
frequency, synchronous buck, DC-DC applications. The
FDMF3030 integrates a driver IC, two power MOSFETs,
and a bootstrap Schottky diode into a thermally
enhanced, ultra-compact, 6x6mm package.
With an integrated approach, the complete switching
power stage is optimized with regard to driver and
MOSFET dynamic performance, system inductance,
and power MOSFET RDS(ON). The FDMF3030 uses
Fairchild's high-performance PowerTrench® MOSFET
technology, which dramatically reduces switch ringing,
eliminating the need for a snubber circuit in most buck
converter applications.
A driver IC with reduced dead times and propagation
delays further enhances performance. A thermal
warning function indicates a potential over-temperature
situation. The FDMF3030 also incorporates a Zero-
Cross Detect (ZCD_EN# pin) for improved light-load
efficiency and provides a 3-state 5V PWM input for
compatibility with a wide range of PWM controllers.
