MAX1724EZK33+T

The MAX1724EZK33+T is a step-up DC-DC Converter for single-cell battery-powered devices. The compact, high-efficiency, step-up DC-DC converter features an extremely 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, this device is ideal for applications where extremely low quiescent current and ultra-small size are critical. Built-in synchronous rectification significantly improves efficiency and reduces size and cost by eliminating the need for an external Schottky diode. All three devices feature a 0.5Ω N-channel power switch. The MAX1724 also feature proprietary noise-reduction circuitry, which suppresses electromagnetic interference (EMI) caused by the inductor in many step-up applications. The family offers different combinations of fixed or adjustable outputs, shutdown and EMI reduction.
