产品详情

Demonstration circuit 1856B-B features the LTM4649EY μModule® regulator, a high performance high efficiency step-down regulator. The LTM4649EY has an operating input voltage range of 4.5V to 16V and is able to provide an output current of up to 10A. The output voltage is programmable from 0.6V to 3.3V and can be remotely sensed with the internal differential remote sensing amplifier. The LTM4649EY is a complete DC-DC point of load regulator in a thermally enhanced 15mm × 9mm × 4.92mm BGA package requiring only a few input and output capacitors.
