Working Principles

The MAX714CPE is a step-up DC-DC converter that utilizes a high-frequency switching regulator to efficiently boost the input voltage to a regulated output voltage. It is specifically designed for use with single-cell NiCd or NiMH batteries.

The IC incorporates a power MOSFET, which acts as a switch, and an inductor to store and transfer energy. The switching frequency of 1.2MHz allows for smaller external components and reduces the size of the overall circuit.

By regulating the duty cycle of the switching regulator, the MAX714CPE maintains a stable output voltage within the specified range, even as the input voltage varies. It also includes protection features such as overcurrent and overtemperature protection to ensure safe operation.

Detailed Application Field Plans

The MAX714CPE is commonly used in portable electronic devices powered by single-cell NiCd or NiMH batteries. Some typical applications include:

1. Handheld GPS devices
2. Portable media players
3. Wireless communication devices
4. Wearable devices
5. Remote control systems
