02.05.2018 · News
Vishay Intertechnology introduced a new ceramic / quartz-based UVC emitting diode for sterilization, sanitation, and purification applications...
Simple single-cell white-LED driver uses improvised transformer
02.04.2018 · Circuits
Jim Grant EDN A white LED delivers a wide color spectrum and better visibility than do monochromatic LEDs. However, a white LED presents a higher forward-voltage drop than do its colorful counterparts and thus poses problems for operation from a single 1.5 V cell...
Toshiba launches small LDO regulator ICs suitable for IoT applications
02.04.2018 · News
New devices combine low quiescent bias current, high ripple rejection and fast transient response Toshiba Electronics Europe released the TCR3UG series of small package, low-dropout (LDO) regulators with an output current of 300 mA, that are suitable for power management of IoT modules, wearable devices and smartphones. Design engineers always need to consider the trade-off between the quiescent bias current, the ripple rejection ratio and load transient response of an LDO...
BCR430U improves efficiency for LED strips with an ultra-low voltage drop linear LED driver IC
02.01.2018 · News
Infineon Technologies releases BCR430U, a constant current linear LED driver IC. The BCR430U provides industry-leading drop performance for regulating LED current in standalone operation. No external power transistor is needed. Typical applications for the BCR430U include LED strips, architectural LED lighting, LED displays as well as retail, appliance and emergency lighting. The voltage drop at the integrated driver IC can go down to 135 mV at 50 mA...

Analog Devices announces the LTC5562, a low power, high performance active double-balanced mixer, capable of 50 Ω matching over a very wide frequency range of 30 MHz to 7 GHz. This versatile mixer can be used in either frequency upconversion or downconversion applications, with outstanding conversion gain of 2 dB...
Circuit limits dV/dt and capacitor inrush at regulator turn-on
01.29.2018 · Circuits
Unusual design constraints sometimes reveal the unfriendly side of everyday components and circuits. A case in point is the design of power-supply-regulation circuitry in which the primary power source has an absolute current-limit specification, such as spacecraft photovoltaic, or “solar,” panels and radioisotope-thermoelectric generators...
