Package options for TV set

CoolMOS™ CE offers a wide range of products for the TV SMPS application and is selected by the world’s leading TV manufacturers due to high quality, reliability and ease-of-use. Together with XDP™ digital power, OptiMOS™, EiceDRIVER™ and other components from Infineon, we offer system solutions as demonstrated by a wide range of reference designs. Our dedication for TV application has been further demonstrated by developing 600V CoolMOS™ CE in TO-220 FullPAK Wide Creepage products mainly for TV application.

Value proposition of 500V, 600V and 650V CoolMOS™ CE for TV applications

For the AC-DC power supply in TV applications, CoolMOS™ CE devices come in different voltage classes of 500V, 600V and 650V so as to be used in both PFC and LLC stages. The CoolMOS™ CE devices are offered in different packages such as TO-220 FullPAK, TO-220 FullPAK Wide Creepage, DPAK and SOT-223. This variety enables customer to use these packages in different stages of the power supply to ease the PCB layout design and manufacturing.

As an example, the TO-220 FullPAK can be used in the top-side PFC stage and the DPAK or SOT-223 can be used in the bottom side LLC stage making the layout simpler, and efficiently meeting the thermal and EMI requirements. When CoolMOS™ CE devices are driven with optimal gate driving techniques, they exhibit low temperature rise and provide high efficiency performance. These devices are robust and are capable of withstanding higher stress under fault conditions. This high reliability feature makes them suitable for operation in environments which have unstable power conditions.

As an example, the stress on the PFC MOSFETs can be high under input line transient or faulty load conditions. The CoolMOS™ CE devices safely carry high peak currents until the PWM controller responds to the transient condition.

Infineon offers a reference design for a 120W TV SMPS which combines the advantages of XDP™ digital power and CoolMOS™ CE to offer the state-of-the-art performance.

The DPAK solution has no concerns on the package height for semi-slim and slim adapter solutions, as its height is far below the allowed height, and it is on the other side of the package, meaning space saving and power density increasing, however better thermal management is required.

The TO-220 FullPAK Wide Creepage increases the creepage distance to 4.25mm compared to 2.54mm for a standard TO-220 package. It fully meets requirements of the EN60664-1 standard that requires at least 3.6mm for open frame electrical power supplies which are often found in LED TV, PC power or industrial power supplies.
