Automotive-grade buck-boost ICs ensure stable performance with low current consumption
ROHM today announced the availability of a buck-boost power supply chipset that provides the lowest current consumption in the industry along with stable performance (transient response characteristics) in automotive ECUs (Electronic Control Units) for cluster panels and gateways used in start-stop vehicle systems. The chipset integrates a buck DC/DC converter with boost functionality (BD8P250MUF-C) and a […]
DC-DC converters boost RFPA, GaN-transistor-based applications
Flex Power Modules announces the PKB4216HDPI, the latest model in its series of DC-DC converters aimed at Radio Frequency Power Amplifier (RFPA) applications in the telecom market segment. Following on from the recently introduced 750W PKJ4000 series, the PKB-D is a high-density converter in the industry standard eighth-brick format with an output of 50V at […]
AC-DC converter module delivers 10 kW in power tablet configuration
Vicor Corporation has announced a 3-phase, AC-DC converter module (“RFM”), capable of delivering 10kW of regulated 48VDC in a power tablet configuration measuring 9.4 x 5.9 x 0.6in (24 x 15 x 1.5cm). The RFM provides a power-factor-corrected, regulated, and isolated DC output with integrated filtering and built-in fault protection for redundant operation. The RFM […]
Low-profile DOSA converters hit 99% efficiency
New power modules offer one of the highest power densities in a DOSA footprint on the market with a profile of only 3.75 mm. They provide either 1, 2, 3, or even 6 A in the same-sized package for scalability. The 6-A module has at least 50% higher power density than its peers on the […]
Chassis-mount DC-DC converters for railway applications get pluggable connectors
Bel Power Solutions announces an extension to the RCM Series, 150 W to 1000 W chassis-mount DC-DC converters, with an optional pluggable connector version. The pluggable connectors are an alternative to the standard cage clamp terminals, that lowers the risk of reverse polarity connection and supports the integration of ready-made cable harnesses during installation, as well […]
