Analog Devices MAX1722, MAX1723, and MAX1724 DC-DC Converters are compact, high-efficiency, step-up DC-DC converters available in tiny TSOT-5 and µDFN-6 packages. These devices feature a low 1.5µA quiescent supply current to ensure the highest possible light-load efficiency. Optimized for operation from one to two alkaline or nickel-metal-hydride (NiMH) cells, or a single Li+ cell, these devices are ideal for applications where extremely small quiescent currents and ultra-small sizes are critical. The built-in synchronous rectification significantly improves efficiency and reduces size and cost by eliminating the need for an external Schottky diode.
