Maxim Integrated MAX1605ETT+ Step-Up DC-DC Converter

The MAX1605ETT+ is a high-efficiency, compact step-up DC-DC converter from Maxim Integrated designed to provide a versatile power solution for battery-powered and low-voltage systems. This tiny device is capable of delivering a fixed or adjustable output voltage from a single-cell battery input, making it an ideal choice for portable electronics, handheld devices, and other applications where space and efficiency are critical.

Encased in a small 6-pin TDFN package, the MAX1605ETT+ offers a space-saving footprint that is particularly beneficial for designs where board real estate is at a premium. Despite its diminutive size, this converter does not compromise on performance. It operates over a wide input voltage range from 0.7V to VOUT, which allows it to boost the voltage from even deeply discharged batteries.

The device features a high switching frequency of 600kHz, which enables the use of tiny, low-profile inductors and capacitors, further reducing the overall solution size. The MAX1605ETT+ also incorporates an internal synchronous rectifier, which enhances efficiency by eliminating the need for an external Schottky diode. This efficiency, which can reach up to 87%, helps to extend battery life in portable applications.

With its internal compensation and soft-start features, the MAX1605ETT+ simplifies design complexity and minimizes external component count. Additionally, it includes a logic-controlled shutdown mode that reduces the quiescent current to a mere 0.1µA, further conserving battery life when the device is not in active use.

The MAX1605ETT+ also provides built-in safety features such as over-temperature protection and current-limiting to safeguard the device and the application it powers. These protections ensure reliable operation under a variety of conditions.

In summary, the Maxim Integrated MAX1605ETT+ is an excellent choice for designers seeking a small, efficient, and reliable step-up converter. Its combination of high-efficiency performance, compact size, and user-friendly features make it a versatile component for a wide range of power supply applications.
