Constant current linear LED driver IC improves efficiency for LED strips

The BCR430U constant current linear LED driver IC’s drop performance regulates LED current in standalone operation for LED lighting. No external power transistor is needed, says Infineon Technologies. Typical applications for the BCR430U include LED strips, architectural LED lighting, LED displays and retail, appliance and emergency lighting.

The voltage drop of the integrated driver IC can go down to 135mV at 50mA. This improves overall efficiency and provides the voltage headroom required to compensate for LED forward voltage tolerances and variances in the supply voltage, explains Infineon, for more flexibility in lighting design. Using the BRCU430U, additional LEDs can be added to lighting designs without changing the supply voltage.

The LED driver current ranges between five and 100mA, and can be easily adjusted via high Ohmic resistor on a dedicated pin. The supply voltage ranges between 6.0 and 42V. For safe and reliable operation and to extend the LED lifetime, a smart over-temperature controlling circuit reduces the LED current when the junction temperature is very high.

The BCR430U is available now in a SOT-23-6 package.

Alzheimer’s Wearable Assistant

A smartwatch with fall and location detection, reminders and more, designed to help you or your loved one with Alzheimer’s!

When I saw Infineon’s Sensor Hub Nano, it appeared to be a good candidate in such a project, because of its very small size and BLE capabilities. With the accurate pressure sensing, it could be used to detect if the patient has fallen and also tell where exactly the patient is in the house.

Online prototyping with A/D simulation, in Infineon Designer

161028edne-infineon-designer

Infineon Technologies’ Infineon Designer, introduced at the 2016 electronica trade fair, is presented as the first online prototyping engine combining analogue and digital simulation functionalities in an internet application. By Graham Prophet@ edn.com:

Requiring a web browser only, it is an aid to designers in selecting the right product for a defined application. Infineon Designer works intuitively in a very short time, and neither installation nor licenses are needed. The program features application circuits in the domain of Industrial Power, Lighting, Motor Control and Mobile/RF frontend design. It enables analogue/digital co-simulation of the 32-bit XMC1000 industrial microcontroller ARM Cortex-M0 series, using the free-of-charge code generation platform DAVE.
