The 2.4GHz RF front end module (FEM) nRF21540 from Nordic Semiconductor is a „plug and play“ range extender that improves range and connection robustness, when combined with the multiprotocol wireless SoCs of nRF52 and nRF53 Series or other radios. It requires just a minimal amount of external components. The nRF21540 is available at www.rutronik24.com.
The new Recom LED driver modules of the RCDE-48 series are suitable for strings of up to 15 high brightness LEDs and offer analog or PWM (Pulse Width Modulation) deep dimming. They provide a wide input voltage range and a constant current output. The LED drivers are available at www.rutronik24.com.
The SiSS12DN 40V N-Channel MOSFETs from Vishay are designed to increase power density and efficiency in power conversion topologies. They are available in a compact 3.3x3.3mm PowerPAK 1212-8S package and deliver the lowest output capacitance (Coss) in the sub-2-mΩ class. The MOSFETs are available at www.rutronik24.com.
With the NJW4750 NJR presents one of the smallest 4-channel Power Management ICs on the market. The space-saving 3.4x2.6mm EQFN26 package incorporates three buck regulators and a LDO (low dropout) for precise voltage regulation. The NJW4750 and the matching evaluation board are available at www.rutronik24.com.
Fuses are used in many fields of power electronics. Until recently, cables, consumers and voltage sources were generally protected by safety fuses. Using semiconductors brings advantages.
