The working principle of the AP1120SBL-13 is based on the Buck-Boost Switching Topology. The voltage regulator utilizes a synchronous buck-boost switching circuit, allowing it to provide a constant output voltage regardless of the input voltage. During buck mode, the device creates a stable output voltage by switching the converter at a fixed frequency. During boost mode, the device switches the converter at a lower frequency, allowing it to step-up the input voltage. This ensures that the output voltage is not affected by the input voltage, providing a stable and reliable source of power.

In addition, the device includes built-in protection circuitry to protect against current overload and overheating. The device also includes a low-noise voltage reference, as well as a soft-start and auto-restart circuit to ensure a smooth start-up, ensuring optimal power delivery and continuous operation of the device.
