MAX5097 Overview
The MAX5096/MAX5097 easy-to-use, Dual Mode™, DC-DC converters operate as LDO (low dropout) or switch-mode buck converters. At a high output load, the converters operate as high-efficiency pulse-widthmodulated (PWM) switch-mode converters and reduce the power dissipation. The devices switch to a low-quiescent-current (IQ) LDO mode of operation at light load.
