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.
REALLY Smart Wearables Customize Their Power Supply
An integrated buck-boost converter provides a convenient way to power system peripherals that require voltages higher and/or lower than the battery voltage and is optimized for optical sensing systems such as optical heart rate (OHR)/PPG and SpO2 measurements. Output noise is minimized to provide the least impact possible on sensitive measurements in such systems. The addition of DVS offers further power savings during favorable measurement conditions.
Unleash the Full Potential of Your Micro Speakers
This design solution discusses the barriers to high-quality sound from micro speakers due to their size limitations. Maxim’s Dynamic Speaker Management Sound Studio GUI overcomes these barriers, simplifying design and improving time to market. The DSM algorithm is integrated into a fixed-function DSP to alleviate the complexities of programming. DSM, based on MAX98390 Class DG audio amplifier, significantly increases loudness (SPL) and bass response from micro speakers while maximizing efficiency for longer battery operation.
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.
