Demonstration circuits feature DC-DC point-of-load regulator in BGA package

06-03-2019 | Analog Devices | Design & Manufacture

Analog Devices DC2665A-A/B Demonstration Circuits feature the LTM4626 (A), or LTM4638 (B) ┬ÁModule regulator. The LTM4626 is a complete DC-DC point-of-load regulator in a thermally enhanced 6.25mm x 6.25mm x 3.87mm BGA package.

The LTM4626 has an operating input voltage range of 3.1V to 20V. The regulator produces an output current up to 12A. The LTM4638 is a complete DC-DC point-of-load regulator in a thermally enhanced 6.25mm x 6.25mm x 5.02mm BGA package. The device provides an operating input voltage range of 3.1V to 20V and produces an output current up to 15A. The output voltage is programmable from 0.6V to 5.5V and can be remotely sensed. The stacked inductor design enhances thermal dissipation and significantly decreases the package area. Output voltage tracking is offered through the TRACK/SS pin for supply rail sequencing. External clock synchronisation is provided through the SYNC/MODE pin. For high efficiency at low load currents, select DCM mode operation using the MODE jumper (JP7) in less noise sensitive applications.
