Micrel Launches New Family of Miniature, Efficient, Low-Profile, DC-DC Power Modules

Micrel Launches New Family of Miniature, Efficient, Low-Profile, DC-DC Power Modules
Micrel introduced the MIC33163/MIC33164 (1A) and MIC33263/MIC33264(2A) a family of low-profile step down power modules capable of 100 percent duty cycle and operating with an input voltage range from 2.7V to 5.5V. These compact modules integrate a synchronous buck converter with an inductor into a 2.5mm x 3mm x 1.1mm (MIC33163/4) and 2.5mm x 3mm x 1.9mm (MIC33263/4) QFN package. These complete power solutions are ideal for use in numerous applications including wireless modules, solid state drives, wearable devices, and camera modules. Incorporating Micrel's proprietary FleaFET technology and the Company's HyperLight Load® control architecture, these devices can operate up to 4MHz with excellent light and full load efficiency (up to 88 percent at 10mA and over 93 percent peak efficiency). This architecture provides an ultra-fast load transient response that minimizes output capacitance thereby reducing total board space to just 4.6mm x 7mm. With such a small footprint and 100 percent duty cycle capability, these power modules offer an efficient alternative to linear regulators. The MIC33163/4 and MIC33263/4 are available in volume with 1,000 quantities pricing starting at $1.32 and $1.70, respectively.

4kW PCUs offer low noise and ripple

4kW PCUs offer low noise and ripple
Glassman High Voltage has released a series of 4kW open stack PSUs. The air-insulated LH series of PSUs feature low noise and ripple, which is typically less than 0.1% peak to peak of rated voltage at full load. By using air as the primary dielectric medium, weight is minimised and servicing is made easy as no oil or other encapsulation is used.
