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

 

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.

How to Efficiently Power Your Smart Gas/Water Meter

 

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.

开关转换器建模和实验室测量的精度比较?

 

开关转换器建模和实验室测量的精度比较?
Maxim的开关转换器模型和仿真受限于典型值,而更完整的最终设计构思要求我们考虑模型无法顾及的硅变化。在我们的研究中,电容或电感变化等非理想因子对压降的贡献为+/- 10mV (3.3V标称值的0.3%),说明在仿真期间需要考虑可预期的物理元件变化。
