LT3999 36V, 1A 1MHz Push-Pull DC/DC Driver with Duty Cycle Control - Video Product Brief
Nov 18th 2014
The LT®3999 is a monolithic, high voltage, high frequency DC/DC transformer driver providing isolated power in a small solution footprint.
The LT3999 has two 1A current limited power switches that switch out of phase. The duty cycle is programmable to adjust the output voltage. The switching frequency is programmed ...
Minimizing Switching Regulator Residue in Linear Regulator Outputs
Mar 21st 2011
Linear regulators are commonly employed to post-regulate switching regulator outputs. Benefits include improved stability, accuracy, transient response and lowered output impedance. Ideally, these performance gains would be accompanied by markedly reduced switching regulator generated ripple and spikes. In practice, all linear ...
Measuring Switching Regulator Noise
Jun 15th 2009
The universal application of switching regulators, combined with the powered systems potential for supply noise sensitivity, mandates the need for a reliable noise measurement technique. Actually, switching regulator "noise" isn't really noise at all, but coherent, high frequency residue directly related to the regulators switching. ...
How To Build a Low Noise Power Supply for High Voltage (i.e. 100V up to 1000V) Transducers

A Kilovolt with 100 Microvolts of Noise
Photomultipliers (PMT), avalanche photodiodes (APD), ultrasonic transducers, capacitance microphones, radiation detectors and similar devices require high voltage, low current bias. Additionally, the high voltage must be pristinely free of noise; well under a millivolt is a common ...
