Optimizing the energy efficiency of converters and controllers
Here’s how to evaluate energy efficiency associated with components that make up widely used power conversion circuitry. FRANK DE STASI, MATHEW JACOB, TEXAS INSTRUMENTS INC. IN SOME WAYS, selecting a module, converter or controller for power conversion resembles deciding whether to take a flight, board a train, or drive from point A to B. Once […]
12:1-input quarter-brick dc/dc converters key on railway apps
Two 40-W and 60-W dc/dc converter series come in quarter-brick packages with an ultra-wide input voltage range of 14 to 160 Vdc making them a good candidate for railway rolling stock applications and high voltage battery systems. The 12:1 input voltage range of RECOM’s RP40Q-RUW and RP60Q-RUW series covers all input voltages from nominal 24 […]
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 […]
Bi-directional synchronous buck-boost controllers
Renesas Electronics announces an innovative new family of bidirectional four-switch synchronous buck-boost controllers. The ISL81601 and ISL81401 are the industry’s only true bidirectional controllers that sense peak current at both ends and provide a cycle-by-cycle current limit in both directions while in buck or boost mode. The controllers generate point-of-load (POL) and voltage rail conversions […]
