DC/DC converters incorporate inductors to shrink IoT power supply size
Designers can now extend battery life and reduce size in space-constrained IoT devices with two nanoPower modules with built-in inductors from Analog Devices, Inc. Both products are part of Analog Devices’ Essential Analog family of efficient power ICs. The MAXM38643 1.8V to 5.5V input, 330nA quiescent current (IQ), 600mA buck module, and the MAXM17225 0.4V to 5.5V input, […]
Don’t rush to choose rechargeable batteries…at least, not yet
Using energy harvesting and a rechargeable battery to power a remote wireless IoT node seems like an obvious and straightforward solution, but there are some unique aspects to consider. Don’t get me wrong: I really like rechargeable batteries; in fact, I like them a lot. Whether based on lead-acid, nickel-cadmium, lithium-ion, or other chemistry, our […]
Power inductors feature semi-shielded wirewound construction
Bourns, Inc. released its Model SRN2012T semi-shielded power inductor series. The new inductors employ wire-wound construction on a ferrite core to offer high inductance and Q values. They also offer a superior self-resonant frequency plus low DC resistance in a compact size with an operating temperature range of -40 to +125 °C. Such features make this series […]
Buck/boost converter boasts super-low quiescent current, targets battery powered apps
Texas Instruments introduced a new bidirectional buck/boost converter with an ultra-low quiescent current (IQ) of 60 nA – one-third the IQ of competing boost converters. The TPS61094 buck/boost converter integrates a buck mode for supercapacitor charging while providing ultra-low IQ, enabling engineers to extend battery life by as much as 20% when compared to commonly used hybrid-layer […]
ESD protection devices ensure signal integrity for USB4
Nexperia announced two PESD5V0R1BxSF extremely low clamping and capacitance bidirectional Electrostatic Discharge (ESD) protection diodes. Based on Nexperia’s TrEOS technology with active silicon-controlled rectification, the devices ensure optimal signal integrity for USB4 (up to 2 x 20 Gbps) data lines on laptops and peripherals, smartphones, and other portable electronic equipment. The PESD5V0R1BDSF is optimized for low clamping […]
IoT PMIC uses a single inductor to power multiple rails
The new MAX77659 single-inductor multiple-output (SIMO) power management IC (PMIC) with integrated switch-mode buck-boost charger from Analog Devices, Inc. charges wearables, hearables, and Internet of Things (IoT) devices faster and in less space than any other PMIC available today. The MAX77659 SIMO PMIC delivers over four hours of playtime after a short, ten-minute charge, and […]
Miniature supercapacitors qualified for automotive uses
KEMET announces its new high-performance supercapacitors for automotive electronics, the FMD, and the FU0H series. This series delivers 1,000 hours at 85°C/85% RH-rated voltage and operating temperature ranging from -40°C to 85°C. The FMD series offers the highest lifetime with up to 4,000 hours. These supercapacitors are qualified for an automotive testing protocol. These capacitors […]
All-metal current-sense chip resistors feature 1-W power rating
IoT and Robotics require high efficiency and small size to maximize functionality. For current sensing, this means high power in small case sizes and low resistance values. The CSSH0805 from Stackpole is an all-metal chip resistor with a 1W power rating, resistance values down to 0.5 milliohms, and TCR ranging from 50 ppm to 100 […]
Wirewound chip inductors feature low dc resistance, high Q values
Bourns, Inc. announced the CWF1610 and CWF2414 Chip Inductor Series. These inductors employ wire-wound construction on a ferrite core to offer high values of inductance, Q values, and self-resonant frequency, plus low DC resistance in a compact size with an operating temperature range of -40 to +125 °C. These features make this series ideal for RF signal processing, resonant […]
