DC-DC Converters feature integrated heat sink.

Measuring 7.8 x 5.0 x 1.5 in., VFK400 Series provides 400 W output power, accepts 4:1 input, and can support either 10-36 or 18-75 Vdc isolated input voltages. Chassis-mount units are available in 3 regulated output voltage versions of 12, 24, and 48 Vdc. Converters provide remote sense and remote on-off control as well as over-temperature, over-current, and input transient voltage protection....

MILPITAS, CA - - Linear Technology Corporation announces the LT3748H, a high input voltage isolated flyback DC/DC controller with guaranteed operation for junction temperatures as high as 150°C. This device significantly simplifies the design of an isolated DC/DC converter since there is no requirement for an opto-isolator, third winding or signal transformer for feedback, as the output voltage...
