The MAX1722EZK is a compact, high-efficiency step-up DC-DC converter designed for applications where low quiescent current and small size are critical. It operates from one to two alkaline or NiMH cells, or a single Li+ cell.
Key electrical specifications include an extremely low 1.5µA quiescent supply current, up to 90% efficiency, and an output voltage accuracy of ±1%. The device supports an input voltage range of 0.8V to 5.5V and can deliver up to 150mA of output current. It also features a guaranteed startup voltage of 0.91V for the MAX1722/MAX1724 models.
This converter utilizes built-in synchronous rectification, eliminating the need for an external Schottky diode and improving efficiency. The MAX1722 and MAX1724 models include proprietary noise-reduction circuitry to suppress electromagnetic interference (EMI). The device is available in a tiny, 5-pin thin SOT23 package with a maximum height of 1.1mm, making it ideal for space-constrained designs.
Applications for the MAX1722EZK include pagers, remote controls, remote wireless transmitters, personal medical devices, digital still cameras, single-cell battery-powered devices, low-power hand-held instruments, MP3 players, and personal digital assistants (PDAs).
