MCP87050
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
)
• Fast Switching
• 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 MCP87050 is an N-Channel power MOSFET in a
popular PDFN 5 mm x 6 mm package. Advanced
packaging and silicon processing technologies allow
the MCP87050 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 Figure of Merit of the
MCP87050 allows high efficiency power conversion
with reduced switching and conduction losses.
