MCP87090
Features:
• Low Drain-to-Source On Resistance (R
DS(ON)
)
• Low Total Gate Charge (Q
G
) and Gate-to-Drain
Charge (Q
GD
)
• Low Series Gate Resistance (R
G
)
• Capable of Short Dead-Time Operation
• RoHS Compliant
Applications:
• Point-of-Load DC-DC Converters
• High Efficiency Power Management in Servers,
Networking, and Automotive Applications
Description:
The MCP87090 is an N-Channel power MOSFET in a
popular PDFN 5 mm x 6 mm package, as well as a
PDFN 3.3 mm x 3.3 mm package. Advanced
packaging and silicon processing technologies allow
the MCP87090 to achieve a low Q
G
for a given R
DS(ON)
value, resulting in a low Figure of Merit (FOM).
Combined with low R
G
, the low FOM of the MCP87090
device allows high efficiency power conversion with
reduced switching and conduction losses.
