Examples of applications where the BQ51013AYFPT may be a suitable choice are portable medical sensors, health monitoring devices, hearables, wearables, ultra-low power microcontrollers, energy harvesting applications, energy harvesting systems, and any other applications where high efficiency and small physical size is desired.

Working Principle

The BQ51013AYFPT is an integrated power delivery system that combines the features and benefits of a high-efficiency buck-boost converter, a single inductor multiple output (SIMO) converter, and a low-power 1.8V linear regulator. The buck-boost converter is designed to operate efficiently over a wide range of voltage and current levels. The SIMO converter is designed to provide greater power delivery efficiency than a traditional multiple output switching regulator, while still operating at a low noise level. Finally, the 1.8V linear regulator is designed to provide a stable output voltage in extremely low power applications.

The device has two power supply pins that support a VDD input voltage range of 2.7V to 6.0V. This allows the device to operate in applications that require the input voltage to vary over a wide range, such as an energy harvesting system. The device also has two output pins that support an output voltage range of 0.5V to 5.5V. The output voltage is adjustable by controlling the output current flow via pins dedicated for this purpose. This allows quick and efficient control over the output current, allowing the system to adjust to various power delivery needs.

In addition, the BQ51013AYFPT supports power tracking, which allows the device to dynamically adjust its output current to match the input voltage and output voltage. This feature helps provide greater power efficiency and reduce power requirements for the system. Finally, the device features a built-in over-current protection circuit, which helps protect the system by limiting the output current when it exceeds a certain level.

BQ51013AYFPT is a powerful and efficient solution for ultra-low power portable systems and other applications where efficient power delivery and space-constrained operation are desired. The combination of its buck-boost, SIMO, and linear regulator technologies enable the device to provide maximum power delivery efficiency and flexibility in a small package.
