Infineon Technologies AG (FSE: IFX/OTCQX: IFNNY) has now moved towards the smallest automotive electronics power supply. As the first chip manufacturer, Infineon has created a dedicated flip-chip packaging production process that fully meets the high quality requirements of the automotive market. Infineon is now launching its first related product: the linear regulator OPTIREG?TLS715B0NAV50.

With flip-chip technology, ICs can be mounted upside down in a package. Thermal conductivity can be improved by a factor of 2-3 by having the heated part of the IC facing the bottom of the package and closer to the PCB. Its higher power density significantly reduces product size compared to traditional packaging technologies.

Micro power supply: Infineon’s first flip-chip dedicated to automotive applications goes into production

Thanks to dedicated automotive flip-chip technology, the OPTIREG® TLS715B0NAV50 is more than 60% smaller than the reference product

The new linear regulator from Infineon (in the TSNP-7-8 package, 2.0 mm x 2.0 mm) is 60 smaller than the existing reference product (in the TSON-10 package, 3.3 mm x 3.3 mm) % above, while the thermal resistance remains the same. This makes the new device particularly suitable for applications where board space is very limited, such as radar and cameras. The OPTIREG TLS715B0NAV50 operates at 5V and has a maximum output current of 150 mA.

Flip-chip technology has been used in consumer and industrial markets for several years. Given today’s increasingly stringent space requirements (especially with the increasing number of radars and cameras), automotive electronics also require smaller power solutions – but at the same time higher quality requirements. In order to provide best-in-class flip-chip quality, Infineon does not rely on subsequent certification of existing consumer and industrial products, but rather on a dedicated production process for automotive devices.

In the future, Infineon will enhance its portfolio of automotive power supplies in the OPTIREG family with flip-chip technology. Infineon plans to apply the technology to switch-mode regulators and power management ICs.
