Resistor-programmed switching-regulator IC goes rail to rail down to 0V

摘要

Designers must often choose whether to use a low-dropout regulator or a switcher and choose whether to use one large regulator or several small ones. With the LXC3600 synchronous buck regulator from Linear Technology, you have another option: a dc/dc regulator that you can easily parallel with other LTC3600s for greater current-output capability and that you can program down to 0V.
