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 R_DS(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.
Applications
