DC3107A

DC3107A is an evaluation board that features LTM®4640 μModule® (micromodule) regulator, high performance, high-efficiency step-down regulator. The LTM4640 is a complete DC-to-DC point-of-load (POL) regulator in a thermally enhanced 6.25mm × 6.25mm × 5.17mm BGA package. The LTM4640 has an operating input voltage range of 3.1V to 20V and provides an output current of up to 20A. The output voltage is programmable from 0.6V to 3.3V and can be remotely sensed. The stacked inductor design improves thermal dissipation and significantly reduces the package area. Output voltage tracking is available through the TRACK/ SS pin for supply rail sequencing. External clock synchronization is available through the SYNC/MODE pin. For high efficiency at low load currents, select discontinuous-conduction mode operation using the MODE jumper (JP7) in less noise-sensitive applications. Refer to the LTM4640 data sheet and read this user guide before working on or modifying the DC3107A evaluation board.
