Applications of Rigid-Flex PCB in Electronic Products
Rigid-flex PCB has a wide range of applications, such as it can be used in a variety of common electronic products in common life, but also can be installed in high-end aircraft armed systems...
Smallest data converters deliver high integration and performance
Texas Instruments introduced four tiny precision data converters, each the industry's smallest in its class. The new data converters enable designers to add more intelligence and functionality, while shrinking system board space...
High Efficiency, 15V Rail-to-Rail Output Synchronous Step-Down Regulator Can Source or Sink 5A
The LTC3623 is a high efficiency, monolithic synchronous step-down regulator capable of sourcing or sinking up to 5 A of continuous output current from an input voltage range of 4 V to 15 V. Its compact 3 mm × 5 mm QFN package incorporates an abundance of features including a low EMI Silent Switcher architecture...
Ultra-low Power Omnipolar Hall Effect Sensors from Diodes Incorporated Deliver Market-Leading Stability Over Wide Operating Range
Diodes Incorporated introduced the AH1911/21 digital Hall effect sensors, which combine market-leading stable operating and release points with ultra-low power operation. The 3rd generation devices will respond to either polarity of magnetic field and use a ‘hibernating clock’ system...
High-side driver has fault protection
High-side drivers find common use in driving grounded solenoid coils and other loads. Short-circuit protection for such drivers is essential for avoiding damage from wiring faults and other causes. Polymer fuses are generally too slow, and discrete current-limiting circuits are large and cumbersome...
Dialog Semiconductor Introduces First Fully-Integrated Nanopower PMICs for Low-Power IoT Applications
Dialog Semiconductor unveiled its first fully-integrated nanopower PMICs for IoT applications, the DA9070 and DA9073. The new, more powerful PMICs build on the success of Dialog’s first nanopower offerings...
Voltage Reference Bests Zener Diode as Low-Current Bias Source
Zeners are commonly used as low-current sources for bias voltage functions, but the proper voltage reference can give the same result and with much-lower dissipation and no performance tradeoffs. There are times when you need to bias a low-current load and simply didn’t want to add another voltage regulator...
