Linear Technology’s latest low noise DC-DC regulators in the µModule range of encapsulated surface-mount plastic packaged devices with internal inductor, Mosfets and compensation network are designed to attenuate both radiated energy and conducted wideband harmonic energy. 

The LTM4606 is designed to regulate outputs from 0.6V up to 5V and has been verified in high speed multi-gigabit-per-second digital data transmission in serialiser-deserialiser and RocketIo applications.

The LTM4606 and LTM4612 are housed in a 15mm x 15mm x 2.8mm LGA (land grid array) package weighing less than 2g.  The LTM4606 operates from a 4.5V to 28V input supply, regulates an output voltage from 0.6V to 5V and delivers up to 6A to the load.

The LTM4612 operates from a 5V to 36V input supply, regulates an output voltage from 3.3V to 15V and delivers up to 5A to the load. They are both characterized for operation over the -40 to 125ºC E and I grade temperature range as well as over the wider temperature range of -55 to 125ºC (internal temperature) MP grade.

The regulator module’s ultra low noise operation is achieved by controlling the slew rate of the Mosfet gate drive, adding input pi-filters, careful layout and shielded inductor.
