Description

Maxim Integrated's MAX1694EUB+ Step-Up DC-DC Converter

The MAX1694EUB+ from Maxim Integrated is a high-efficiency, compact, step-up DC-DC converter designed for applications requiring voltage conversion from lower to higher levels. It's an ideal solution for battery-powered devices, as it can boost single-cell batteries to the necessary operating voltages for various circuits within the device.

This versatile converter operates over a wide input voltage range, starting as low as 0.7V and delivering a fixed 5V or an adjustable output voltage. This feature makes it perfect for products that run on single-cell lithium-ion, alkaline, or NiMH batteries. The MAX1694EUB+ is housed in a space-saving 10-pin µMAX package, which is highly valued in portable applications where space is at a premium.

Efficiency is a significant aspect of the MAX1694EUB+, as it can reach up to 96%, ensuring minimal power loss during the voltage conversion process. This high efficiency is achieved through an internal synchronous rectifier and a low quiescent current, which also extends battery life in portable applications.

The device features a 1.2MHz fixed-frequency PWM operation, which allows for small external components, thereby reducing the overall solution size. Additionally, the MAX1694EUB+ includes a logic-controlled shutdown mode that reduces the supply current to just 0.1µA, further conserving battery life when the device is not in active use.

Safety and reliability are also addressed with the built-in over-temperature and current-limit protection features, ensuring the device operates within safe parameters. The MAX1694EUB+ is ideal for a variety of applications, including PDAs, cellular phones, wireless mice, small LCD displays, and portable media players.

In summary, the MAX1694EUB+ is a robust, high-performance step-up converter that provides a compact, efficient, and reliable solution for powering devices that require a higher operating voltage from a lower voltage source.
