Introduction
The LT1616 is a complete fixed-frequency step-down switching regulator in a ThinSOT (1mm thick SOT-23) package. It meets the needs of circuit designers who require a large input voltage range or the smallest solution possible. The LT1616 accepts an input from 3.6V to 25V, produces a low voltage output at 400mA and occupies less than 0.15 in2 of board space. With this wide input range, the LT1616 can regulate a large variety of power sources, from 4-cell ...
