1.4 to 3W dc-dc converters operate from 12V input

May 24, 2021  Stephen Law

TDK LAMBDA CHVM series high voltage output dc-dc converters are capable of operating from a nominal 12V input, and deliver output voltages ranging from 180V to 2,000V. Low output ripple and noise is achieved through the use of a metallic case that provides five-sided shielding to reduce radiated emissions. These non-isolated converters are designed for use in noise sensitive applications, including photomultiplier tubes, photodiodes, scanning electron microscopes, X-ray fluorescence spectrometers, mass spectrometers and ultrasonic probes. Product series comprises of 20 parts, with positive or negative polarity output voltages of 180, 300, 350, 470, 1,000, 1,500 and 2,000V. The maximum output ripple and noise level is just 150mV and typical measurements are between 5 and 50mV.
