CoolMOS™ technology is legendary in the industry dierentiated for its high quality, which has been proven over the past years across billions of devices shipped with continuous improved DPM down to less than 0.10 DPM. Infineon has implemented firm and proven measures from the beginning with design-for-quality program and continuous improvement in production. There is a constant proactive collaboration among technology, design, quality, reliability and manufacturing teams to achieve this result. This eort is above and beyond the fact that all Infineon sites are ISO/TS16949 certified.
CoolMOS™ supply chain – delivery reliability, flexibility and supply security
Our customers value CoolMOS™ not only for its technical merits but also for the outstanding delivery reliability: once a CoolMOS™ order date is committed, more than 96 percent of orders are shipped at or before the committed date. And CoolMOS™ orders are committed to more than 80 percent to the date that the customers request. Security of supply and flexibility to demand changes are focus targets and enabled by a well balanced production network. For example more than 90 percent of our products are qualified for production in at least two back end locations and more than 80 percent of the volumes in two wafer fabs. This enables CoolMOS™ supply chain to react fast to changes in customer and market requirements.

CoolMOS™ CE – smartphone and tablet chargers
Chargers for smartphones and tablets as well as other mobile applications demand for a growing output power at same or smaller form factors, leading to increasing power density, and stringent requirements on thermal management, EMI emissions and overall system cost. For example, many OEMs request a device temperature less than 90°C with an open case and close case temperature less than 50°C.
Infineon recommends its series of 700 V CoolMOS™ CE superjunction MOSFETs for this application, which are used by leading charger OEMs and design houses in their charger applications. Compared to planar MOSFETs the 700 V CoolMOS™ CE oers reduced switching and thus higher eiciency while passing EMI standards and ringing requirements. Several reference designs have been developed by Infineon to help customers to simplify charger design and thus providing fast time-to-market (see reference design selection table at end of section).
Value proposition of 700 V CoolMOS™ CE:
High eiciency, meeting application requirements
More than enough safety margin in thermals, for 10 W-25 W chargers
Good EMI performance – meets the EMI EN55022B standard without extra design-in eort
Easy-to-use product due to good controllability via gate resistor
Large breakdown voltage of nominal 700 V (and additional guard band typical) for safety on voltage spikes
Infineon recommends CoolMOS™ CE in 700 V for charger applications to secure suicient margin for voltage spikes. CoolMOS™ CE products are also available in 650 V and 600 V for use in less sensitive designs.

Infineon CoolMOS™ CE oers higher eiciency and better thermals than planar MOSFETs: When replacing a 1.6 Ω planar MOSFET with an Infineon 2.0 Ω CoolMOS™ CE in a 15 W QC 2.0 charger we measured ≥0.2 percent eiciency improvement. At the same time, the MOSFET temperature was 7°C cooler, showing a clear benefit of using CoolMOS™ CE for charger applications.

CoolMOS™ CE – package options for charger application
IPAK Short Lead and DPAK
Standard packages used in chargers today with excellent reliability and wide usage in the industry
SOT-223 Highly cost optimized surface-mount package with small footprint. The SOT-223 shows slightly worse thermal performance than DPAK, however this can be compensated with little eort by oering a slightly larger copper area (~15 mm²) around the package for heatsinking on the PCB (see page 14, lighting application)
IPAK Short Lead with Isolation Stando:
Innovative package for charger applications providing a defined stando between package and PBC
ThinPAK 5x6
Very flat package (0.8 mm height) package targeting slim charger solutions. Bottom side cooling is applied by many customers, but heat sinking through the top side is also possible
I2PAK
Larger package with better thermal performance than IPAK short lead for more than 20 W charger application. The package carries higher cost yet saves eorts in heat sinking

IPAK Short Lead with Isolation Stando
The new IPAK Short Lead with Mold Stopper will provide a defined stando between package body and PCB for proper cleaning aer wave soldering to avoid leakage current on board level. Mold bumps at the bottom of the package body allow to fully insert the MOSFET into the PCB leaving a well-defined isolation distance of 0.3 mm between the PCB and package body. Creepage distance is increased and production yield is improved as area between package and PCB can eectively be cleaned.

CoolMOS™ CE – notebook adapters
The CoolMOS™ CE series has been widely chosen by leading OEMs in notebook adapters. With ease-of-use, cost competitiveness and short lead time as well as corresponding reference designs, customers can easily design CoolMOS™ CE products in their adapters and have a faster time-to-market.
Value proposition of 600 V and 650 V CoolMOS™ CE for adapters
High eiciency exceeding values achieved with planar MOSFETs
Good thermals, especially for high density, small form factor designs
High breakdown voltage corridor – typical breakdown voltage by far exceeds specified max. value and is higher than typical MOSFETs from other vendors
Easy-to-use product due to good controllability via gate resistor
Infineon’s 35 W adapter powered by IPD60R650CE:
Active-mode eiciency versus AC line input voltage
Infineon’s 35 W adapter reference design has been powered by IPD60R650CE, which oers an eiciency of more than 87 percent and a peak power of 45 W for 2 ms. The dynamic load response is only ±2 percent and standby power is below 100 mW. Customers could modify this board according to their requirements, gaining time-to-market. The board is orderable through Infineon’s sample center.

Optimization for EMI and eiciency/thermals
EMI and eiciency/thermals need a careful trade-o in notebook adapters

Adding additional drain-source capacitor CDS, e.g., 100 pF
Adjusting external RG, e.g., 5 Ω–30 Ω
Optimizing PCB layout for short path from controller to MOSFET gate and a small loop inductance
Adjusting EMI filter (only if other measures are insuicient)
