Power Management ICs

The fifth generation CoolSET™ product family from Infineon offers high performance combined with the latest 700V and 800V CoolMOS™ P7 families in both DIP-7 and DSO-12 packages. The fifth generation CoolSET™ is tailor-made for the auxiliary power supplies for major home appliances, and it can supply up to 42W output power.

Using a novel quasi-resonant implementation, and an intelligent adaptive digital algorithm, the PWM controller can minimize the spread of switching frequencies under different AC line input conditions. This innovative approach allows SMPS designers to develop applications with higher switching frequencies, taking advantage of smaller magnetics and reducing the system BOM cost. To increase system robustness, line input over-voltage protection, and brown-in/brown-out protection has been incorporated into the CoolSET™ family. This high level of integration reduces BOM cost because less external components are required, and less thermal and heat management is necessary due to the high efficiency of the device.

Integrated LED lighting

The development of features beyond just functional lighting in major home appliances is being driven by consumer demand. Current market trends include esthetic features such as ambient illumination and lighting. Integrated Circuits (ICs) provide the technology required to integrate these new features while meeting strict energy requirements.

Infineon offers a broad and cost efficient portfolio of linear and buck LED driver control ICs for LED strips and multichannel LED solutions, driving currents from as low as 10 mA up to 500 mA.
Both LED strips and multichannel LED applications require a constant voltage input, usually up to 60 V. Commonly used in accent lighting , each LED string or channel needs an LED driver IC, usually a linear LED driver IC for up to 250 mA LED current, and a switch-mode LED driver IC for higher LED drive currents.

Infineon’s portfolio for LED strips and multichannel LED: BCR and ILD series.

Both families come with a line-up of regulators with an integrated power stage and a line-up of controllers that allow the utmost scalability via flexible dimensioning of the output stage.
Maximize LED strips and multichannel LED designs with Infineon, and explore these products for more details.


ILDxxxx series
