Analog Devices LTM4668 | Demoboard DC2785A-A

Description

Demonstration circuit 2785A-A features the LTM®4668 μModule® regulator, a Quad 1.2A high efficiency stepdown regulator. DC2785A-A has an operating input voltage range of 2.7V to 17V and can provide an output current of up to 1.5A. The output voltage can be programmed from 0.6V up to 1.8V. The LTM4668 is a complete DC/DC point of load regulator in a thermally enhanced 6.25mm × 6.25mm × 2.1mm BGA package requiring only a few input and output capacitors.External clock synchronization is available through the CLKIN turret. The LTM4668 data sheet must be read in conjunction with this demo manual for working on or modifying demo circuit 2785A-A.
