Power the connected appliances in your home

The latest technological advancements are converting our daily routines into something more convenient, exciting, and interesting. Connected home appliances can now do things such as helping us plan our day. Connected refrigerators can track upcoming expiration dates and create shopping lists. We can remotely turn on the air conditioner, or even use voice control to make a coffee and adjust the lights.

A well-designed and efficient auxiliary power supply provides the stable DC voltage and current that these smart functions require. The intelligent controls embedded in the appliances use this power to drive the smart functionality that makes them a useful part of our connected world.

With Infineon as your partner, you will be able to focus on the functionality which distinguishes your major home appliance designs without worrying about the need to develop complex power supply subsystems. Based on your power and efficiency needs, you can find highly integrated ready-to-use solutions for major home applications, ranging from the lowest cost to the highest efficiency in the given power class.

Recommended components - 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.

Infineon’s products for LED strips and multichannel LED

Infineon’s portfolio of high-quality, and cost-efficient components are the best possible devices for your LED lighting solution. Look no further than on Infineon's two main product families: 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.

Solution I: CoolSET™ + BCRs

Infineon BCRs are suitable for driving currents from 10 to 250 mA. The BCR linear regulators make sure than the driving current is always tightly controlled regardless of operating temperature. This contributes to the longevity and reliability of your application designs even if they are operating under harsh environmental conditions. BCRs are also suitable for PWM dimming at high frequencies, providing flicker-free lighting solutions.

Key Features and Benefits -  BCRs

 • Different break down voltages
 • Very low cost solutions
 • Adjustable output current
 • Ultra- low voltage drop versions
