Analog Devices / Maxim Integrated MAX1722/MAX1723/MAX1724升压型直流-直流转换器
Maxim MAX1722/MAX1723/MAX1724升压直流-直流转换器是一款紧凑、高效、升压型直流-直流转换器，采用5引脚TSOT小尺寸封装。这些器件具有1.5µA超低静态电源电流，提供更高的轻载效率。这些器件优化于1至2节碱性电池、镍氢 (NiMH) 电池或1节锂电池应用。这些直流-直流转换器非常适合用于需要极低静态电流和超小尺寸的应用。内置同步整流器，显著提高了效率并降低了尺寸和成本，且无需外部肖特基二极管。
The Analog Devices MAX1722, MAX1723, and MAX1724 DC-DC Converters integrate a 0.5Ω N-channel power switch. The MAX1722 and MAX1724 also feature proprietary noise-reduction circuitry, suppressing electromagnetic interference (EMI) caused by the inductor in many step-up applications. These devices offer different combinations of fixed or adjustable outputs, shut down, and EMI reduction.
