Seven DC/DC converters suit UAVs, transport and industry
Seven devices in a CHiP have been announced by Vicor. The DCMs are isolated, regulated DC/DC converters, operating from an unregulated, wide range input to generate an isolated DC output.
They have a high frequency, zero voltage switching (ZVS) topology, to deliver high efficiency across the input line range, says the company. Modular DCM converters and downstream DC/DC products support efficient power distribution, providing connectivity from a variety of unregulated power sources to the PoL.
The new devices join CHiP packages announced earlier by the company. There are four new 30V input nominal modules (9 to 50V) in a 3623 CHiP package (1.52 x 0.90 x 0.29inch), which have output voltages of 5.0, 24, 28, and 48V, and power levels up to 160 W, achieving a power density up to 404W/in3.
The is also a 28V input nominal module (16 to 50V range) in a 3623 ChiP package, with a 3.3V output at 120W, a 375 W module with a nominal input voltage of 275V (120 to 420V) and 12V output in a 4623 ChiP package. There is also a 270V input nominal module (160 to 420V range) in a 4623 ChiP package with a 48V output at 500W (1.89 x 0.90 x 0.29inch), achieving a power density of 1,014W/in3.
They are suitable for a variety of applications, including UAV, ground vehicle, radar, transportation and industrial controls.
