Maxim Integrated MAX1703ESE+ Step-Up DC-DC Converter

The MAX1703ESE+ is a high-efficiency, low-quiescent-current step-up DC-DC converter designed and manufactured by Maxim Integrated. This compact and powerful component is ideal for portable electronic devices that require voltage boosting from low-voltage batteries to the levels necessary for powering various circuits within the device.

Enclosed in a space-saving 16-pin Narrow SO package, the MAX1703ESE+ operates from a supply voltage ranging from 0.7V to 5.5V, making it particularly suitable for applications powered by single-cell batteries, such as AA or AAA, as well as lithium-ion and lithium-polymer batteries. This flexibility allows the MAX1703ESE+ to be employed in a broad spectrum of portable electronics, including handheld gaming devices, medical equipment, and personal digital assistants.

One of the standout features of the MAX1703ESE+ is its high efficiency, which can reach up to 92%. This is achieved through an advanced control scheme that minimizes power losses during conversion. The device also includes a low quiescent current of only 5µA, which is crucial for extending battery life in portable applications.

The MAX1703ESE+ is capable of delivering an adjustable output voltage up to 16.5V or a fixed output voltage, depending on the needs of the application. This versatility is further enhanced by its ability to provide up to 2A of output current, making it a robust choice for driving high-current loads such as OLED displays and camera flashes.

Additional features of the MAX1703ESE+ include a 1MHz fixed-frequency PWM operation, which reduces the size of external components, and a low-battery detector that alerts the system when the battery voltage falls below a predefined threshold. Furthermore, the device offers built-in over-temperature and short-circuit protection, ensuring reliable operation and the safety of the components it powers.

Overall, the Maxim Integrated MAX1703ESE+ is a high-performance solution for designers looking to maximize battery life while providing stable voltage supply in space-constrained, portable electronic applications.
