The MAX797HESE+ is an IC (integrated circuit) component manufactured by Maxim Integrated. It is a step-up DC-DC converter with high efficiency and several key features that make it suitable for various applications.
One of the significant features of the MAX797HESE+ is its high efficiency, which enables it to provide a maximum output current of 500mA from input voltages as low as 0.8V. This feature is particularly useful in battery-powered devices where maximizing the power conversion efficiency is crucial for extending the battery life.
Additionally, the MAX797HESE+ offers a wide input voltage range, from 0.8V to 5.5V, allowing it to be compatible with a variety of power sources like single-cell batteries, USB power, or other low voltage sources. The device also incorporates an input undervoltage lockout (UVLO) feature, which protects the circuit by shutting down the converter when the input voltage drops below a specified threshold.
Another key feature of the MAX797HESE+ is its built-in soft-start capability, which allows a controlled and gradual ramp-up of the output voltage during start-up, eliminating any potential issues associated with an abrupt voltage transition. This feature helps in preventing excessive inrush current that may damage sensitive components during power-on.
Furthermore, the MAX797HESE+ provides a high level of design flexibility with multiple pin-selectable output voltage settings available, including 3
