MAX1688ESA+T is a DC-DC switching step-up voltage regulator system developed by Maxim Integrated. It integrates a high frequency voltage regulator meant to convert battery voltage to constant output voltage, specially designed for small and cost-efficient applications.  MAX1688ESA+T is part of Maxim Integrated\'s low-voltage DC-DC switching regulator family, most of the applications falling under the categories of DC-DC power regulation and portable power supplies. This device has various features including low input and output voltage range, wide output voltage range and user-selectable pulse width modulation. This offers improved energy efficiency and reduced size compared to traditional linear regulator designs.MAX1688ESA+T input voltage to be range from 0.8V to 3.6V and the internal load switch allows output voltage range from 1.8V to 5.5V while regulating. It offers a step-up voltage converter integrated with an ultra-low noise, 800mA (600 mA continuous) switch mode step-up converter. It also includes an External Short-Circuit Protection (ESCP) to protect against outputs shorts and an Active-Low Shutdown-Mode Control (ASMC) to reduce power consumption when device is not in use.The system utilizes a capacitor-free topology which is optimized for size and efficiency, while using a synchronous rectifier in order to improve efficiency even further. The MAX1688ESA+T have adjustable frequency of up to 2.2MHz, allowing the device to be used even with small filter components. The Low-Ripple Burst Mode™ operation, meanwhile, reduces quiescent current and improves efficiency at light-load currents. The decreasing size of components in this device help the system make the best use of available space for the application, conserving valuable resources.Another compact and cost-effective feature of this device is the sophisticated Maximum Peak Current Limit (MPCL) control. MPCL keeps the switch current below the specified maximum current level, reducing the risk of thermal stress, current overload and output voltage ripple.The MAX1688ESA+T is a complete system, which can support battery powered systems with a single device. In addition, it also features comprehensive diagnostic functions, such as output overvoltage and open LED warning, as well as additional features such as slope compensation for soft-start output voltage and foldback current limit for short-circuit protection. Its wide operating temperature range(-40°C to 85°C) makes the device suitable for a variety of applications, for example, consumer electronics and mobile devices. All these features, along with the low power consumption make the MAX1688ESA+T an ideal choice for applications where the saving of power and cost are important factors. All these features make the MAX1688ESA+T a perfect choice for applications in need of a reliable step-up voltage converter, allowing system resources to be freed up for other tasks. From battery powered systems to consumer electronics, the MAX1688ESA+T helps minimize time and cost while optimizing power consumption.
