New DC-DC Converters for Noise Sensitive Applications

TDK-Lambda is a global leader in both isolated and non-isolated DC-DC converters. For its Israeli customers, local inventory and local support enable TDK-Lambda to offer optimal solutions for unique needs. Some of these special requirements come from producers of electrical applications that are very sensitive to radiated and conducted noise. These devices include scanning electron microscopes, X-ray spectrometers, photomultiplier tubes, photodiodes, mass spectrometers and ultrasonic probes. TDK-Lambda’s new CHVM series of DC-DC converters was especially developed for such noise sensitive applications. The low output ripple and noise is achieved through the use of a metallic case that provides five-sided shielding to reduce radiated emission (less external filtering is required). These non-isolated converters have programmable output voltages (voltage or resistance). They are capable of operating from a nominal 12V input, with output voltages of 180, 300, 350, 470, 1,000, 1,500 and 2,000V. The converters are certified to IEC/UL/CSA/EN 62368-1 safety standards, and have the CE mark for the Low Voltage and RoHS Directives.
