MCP87055T-U/LC Microchip

MCP87055 High-Speed N-Channel Power MOSFET Features Description Low Drain-to-Source On Resistance (R ) The MCP87055 device is an N-Channel power DS(ON) MOSFET in a popular PDFN 3.3mmx3.3mm Low Total Gate Charge (Q ) and Gate-to-Drain G package. Advanced packaging and silicon processing Charge (Q ) GD technologies allow the MCP87055 to achieve a low Q G Low Series Gate Resistance (R ) G for a given R value, resulting in a low Figure of DS(on) Fast Switching Merit (FOM). Combined with low R , the low Figure of G Capable of Short Dead-Time Operation Merit of the MCP87055 allows high-efficiency power ROHS Compliant conversion with reduced switching and conduction losses. Applications Point-of-Load DC-DC Converters High Efficiency Power Management in Servers, Networking, and Automotive Applications Package Type PDFN 3.3 x 3.3 1 8 S D S 2 7 D S 3 6 D 5 G 4 D Product Summary Table: Unless otherwise indicated, T = +25C A Parameters SymMinTypMaxUnits Conditions Operating Characteristics Drain-to-Source Breakdown Voltage BV 25 V V = 0V, I = 250 A DSS GS D Gate-to-Source Threshold Voltage V 1.11.351.7 V V = V , I = 250 A GS(TH) DS GS D Drain-to-Source On Resistance R 5.7 7 m V = 4.5V, I = 20A DS(ON) GS D 4.7 6 m V = 10V, I = 20A GS D Total Gate Charge Q 11 14 nC V = 12.5V, I = 20A, V = 4.5V G DS D GS Gate-to-Drain Charge Q 4.5 nC V = 12.5V, I = 20A GD DS D Series Gate Resistance R 2.1 G Thermal Characteristics Thermal Resistance Junction-to-X R 66 C/W Note 1 JX Thermal Resistance Junction-to-Case R 3.4 C/W Note 2 JC Note 1: R is determined with the device surface mounted on a 4-Layer FR4 PCB, with a 1 x 1 mounting pad of JX 2 oz. copper. This characteristic is dependent on users board design. 2: R is determined using JEDEC 51-14 Method. This characteristic is determined by design. JC 2012 Microchip Technology Inc.
