  • Three Top Tips For Selecting PCB Spacers
    Selecting the right spacer for your project can be a challenge, so it's essential to consider a number of factors before you commit to purchasing. Luckily, Essentra has over 50 years' experience in developing and manufacturing spacers for PCBs.
  • Testing & Matching PCB Antennas
    scenarios. The typical antenna in the 2.4GHz ISM bands and up is a compromise to begin with because of multiple band requirements and size and space constraints; accordingly the typical SWR may be far more significant than reflection or attenuation from a less than ideal test cable interface. Every device
  • Bootstrap Power Supply for Motor Control
    Bootstrap power supplies can be used to reduce the. number of isolated power supplies or DC-to-DC converters. This helps to reduce cost and the PCB space as. compared to transformer-based power supplies. The. bootstrap output power supply circuit is used to power. the top-bridge gate drives
  • Multilayer Lamination Methods for PTFE-Based PCBs
    Board designers are continually looking for ways to save weight and space in their applications and are moving toward higher count multilayer designs to solve these issues. Historically, PTFE multilayer designs have limited the number of layers within the design due to the ability of board shops
  • Using Low Resistance MOSFETs as Load Switches
    of operation. This function is often overlooked by the designer and its implementation is frequently left until very late in the design stage, when PCB space is at a premium. The MOSFET provides a low resistance path between the battery and the load. When fully turned on, the MOSFET appears and acts like
  • Proper Temperature Measurement and PCB Mounting for DC-DC Power Converters
    Critical applications range from undersea to military ground to commercial and military avionics to deep space. DC-DC converters, point of load converters, EMI filters and other power modules are offered by various manufacturers, all claiming high reliability. The question is, how do you know what
  • Applying the TC1219/TC1220 Inverting Charge Pumps with Small External Capacitor Values
    the luxury of a reasonably low output resistance (25??typical) capable of driving load currents up to 25 mA. However, these larger-value external capacitors are more expensive and require additional printed circuit board (PCB) space than their smaller-valued counterparts. Additionally, the time required
  • The Evolution of Switched Capacitor Backlight Drivers in Mobile Phones
    , and occupy more PCB space. In addition, converters are inherently less efficient in light load applications because their MOSFET gate charge losses and quiescent current losses outweigh MOSFET conduction losses.
