Powerful low noise solutions

Linear Technology introduces two new, DC/DC uModule regulators designed to deliver low noise power by attenuating both radiated energy and conducted wideband harmonic energy. The LTM4606 regulates outputs from 0.6 up to 5V and has been verified for SERDES and RocketIO applications, while the LTM4612 regulates outputs up to 15V. Both models have received CISPR22 Class B certification.

Pricing for 1,000-pieces is $16.50 and $19.89 for the LTM4606EV and LTM4612EV respectively.

Designed to offer a complete system, these DC/DC uModule regulators are encapsulated in a surface-mount package incorporating the inductor, mosfets, regulator IC and compensation network. This eliminates the need for external filters, magnetic shields and ferrite beads.

Both models are housed in a 15 by 15 by 2.8mm land grid array package weighing less than 2g. The LTM4606 operates from a 4.5 to 28V input supply and delivers up to 6A to the load. The LTM4612 operates from a 5 to 36V input supply and delivers up to 5A to the load. They both operate over the -55 to 125degreeC MP grade temperature range.
