MCP87055
High-Speed N-Channel Power MOSFET
Features
Description
• Low Drain-to-Source On Resistance (RDS(ON)
)
The MCP87055 device is an N-Channel power
MOSFET in
a popular PDFN 3.3 mm x 3.3 mm
• Low Total Gate Charge (QG) and Gate-to-Drain
Charge (QGD
package. Advanced packaging and silicon processing
technologies allow the MCP87055 to achieve a low QG
for a given RDS(on) value, resulting in a low Figure of
Merit (FOM). Combined with low RG, the low Figure of
Merit of the MCP87055 allows high-efficiency power
conversion with reduced switching and conduction
losses.
)
• Low Series Gate Resistance (RG)
• 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

Note 1: RθJX is determined with the device surface mounted on a 4-Layer FR4 PCB, with a 1” x 1” mounting pad of
2 oz. copper. This characteristic is dependent on user’s board design.
2: RθJC is determined using JEDEC 51-14 Method. This characteristic is determined by design.
