How to Extend the Run-Time of Your DSLR/DSLM Camera Design
A POL system approach to power distribution within a DSLR/DSLM digital camera saves power by minimizing the PCB traces losses. Scalability is another POL advantage, as a number of small buck regulators can be added or subtracted as needed, depending on the compexity of the digital camera. Accordingly, we propose a high-efficiency, compact buck converter as the basic building block for the digital camera POL architecture.
PMIC Streamlines Automotive TFT-LCD Display Design
TFT-LCD displays dominate the automotive market as they enter a competitive phase with rivaling technologies. In this phase, they can still be highly competitive by achieving higher efficiencies and higher integration in their design. In this design solution, we review a typical, non-integrated TFT-LCD display system and compare it to a highly integrated approach highlighting the latter advantages in terms of BOM and PCB size reduction. With a highly integrated approach, the entire power management system can be implemented with just two ICs, achieving higher competitiveness vs. emerging technologies.
Improve Automotive Exterior LED Lighting with Buck-Boost Average Current Control
Implementing high-power automotive LED exterior lighting poses challenges in terms of switching losses, which affect power efficiency and accurate current control, which affects the LED color and brightness. This article introduces a new LED controller IC, which, thanks to smooth buck-boost operation, minimizes system complexity and losses while its average current control enhances transient response, preserving LED color and brightness.
Triple Punch Extends the Life of Your Smart Factory Indoor BLE Beacon
Artificial intelligence-driven smart factories rely on tracking devices to manage their workflow. See how MAX17222 nanoPower, an efficient voltage regulator boost converter with low shutdown and low quiescent current, helps a smart-factory indoor BLE beacon last two years on a single battery.
How to Efficiently Power Your Smart Gas/Water Meter
Smart meters operate for 10 to 20 years of time remotely and untethered, relying on powerful non-rechargeable lithium-thionyl-chloride batteries. They present a complex power-management design problem with energy sources that include batteries and supercapacitors. In this design solution, we discussed the challenges of powering a smart-meter wireless RF power amplifier. The solution is based on the MAX8815A, an efficient, low shutdown current and compact boost converter, which delivers the required peak current with the help of a supercapacitor.
