DC-DC Converter Family Adds Tighter Voltage Regulation

Vicor has added 25 new products to its family of DC-DC converter modules (DCMs) with tighter output voltage regulation of ±1%. With high power densities of 1,032 W/inches-squared, the new series allows engineers to drive loads requiring tighter regulation with minimal additional circuitry or downstream components.

The DCM ChiP (Converter housed in Package) is a DC-DC converter module that operates from an unregulated, wide range input to generate an isolated, regulated DC output. With its high frequency zero-voltage switching (ZVS) topology, the DCM converter consistently delivers high efficiency across its entire input voltage range.

The new DCMs are used broadly across defense and industrial applications that require tighter output voltage regulation. These applications include UAV, ground vehicle, radar, transportation and industrial controls. The DCM ChiPs are available in M-grade, which can perform at temperatures as low as -55°C.

Digital Pressure Sensors Boost Design Flexibility

All Sensors has announced a new line of digital pressure sensors: the ELVR Series.  The new device series offers OEM customers increased design flexibility for pressure ranges from 2.5 to 75 mbar (1 to 30 inch H2O). The ELVR Series is a direct replacement to First Sensors’ HCLA product line.

Product highlights include an I2C or SPI interface, an analog 0.5 V to 4.5 V output signal, and significantly reduced position sensitivity. All Sensors’ CoBeam2 Technology allows for greater sensitivity while reducing package stress. The ELVR sensors can communicate directly with microcontrollers, eliminating the need for additional A/D converters. ELVR available at 3 V and 5 V supply voltage. the ELVR series is well suited for portable applications. A wide range of miniature SIP and DIP package options allows for flexible and space-saving PCB-mounting. Devices are available in bidirectional and unidirectional 2.5, 12.5, 25, 50 and 75 mbar pressure ranges.(inches of water)
