The LTC7103 is a 105V, 2.3A, synchronous step-down regulator that incorporates a proprietary architecture in a small 5mm x 6mm QFN package to achieve ultra-low EMI/EMC emissions without sacrificing efficiency. Operating from an input voltage between 4.4V and 105V, the LTC7103 has a no-load input current of only 2μA when regulating 48Vin to 3.3Vout.

Utilizing a unique average current mode architecture, the LTC7103 offers fast and accurate output current programming and monitoring without the need for an external sense resistor. Eight, pin-selectable fixed output voltages and optional internal loop compensation save board space and quiescent current while making the LTC7103 extremely easy to use.
