MCP87055 High-Speed N-Channel Power MOSFET Features Description • Low Drain-to-Source On Resistance (RDS(ON)) • Low Total Gate Charge (QG) and Gate-to-Drain Charge (QGD) • Low Series Gate Resistance (RG) • Fast Switching • Capable of Short Dead-Time Operation • ROHS Compliant The MCP87055 device is an N-Channel power MOSFET in a popular PDFN 3.3 mm x 3.3 mm 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. 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 S 1 8 D S 2 7 D S 3 6 D G 4 5 D Product Summary Table: Unless otherwise indicated, TA = +25˚C Parameters Sym Min Typ Max Units Conditions Drain-to-Source Breakdown Voltage BVDSS 25 — — V VGS = 0V, ID = 250 µA Gate-to-Source Threshold Voltage VGS(TH) 1.1 1.35 1.7 V VDS = VGS, ID = 250 µA Drain-to-Source On Resistance RDS(ON) — 5.7 7 mΩ VGS = 4.5V, ID = 20A — 4.7 6 mΩ VGS = 10V, ID = 20A Operating Characteristics Total Gate Charge QG — 11 14 nC VDS = 12.5V, ID = 20A, VGS = 4.5V Gate-to-Drain Charge QGD — 4.5 — nC VDS = 12.5V, ID = 20A RG — 2.1 — Ω Thermal Resistance Junction-to-X RθJX — — 66 ˚C/W Note 1 Thermal Resistance Junction-to-Case RθJC — — 3.4 ˚C/W Note 2 Series Gate Resistance Thermal Characteristics Note 1: 2: 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.

DS25133B-page 14 Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products.
