The AP3407AKTR-G1, classified as a DC DC Switching Regulator in the family of PMIC- Voltage Regulators, is a power management integrated circuit (PMIC) designed specifically to be used in most automotive and industrial applications. It enables efficient, smooth, accurate and stable power supply output. The IC features a synchronous buck topology and is highly efficient, providing up to 93% of conversion efficiency with a minimal output voltage ripple, making it ideal for applications that require a reliable, low-noise DC output.

The AP3407AKTR-G1 operates from an input voltage range of 4.5V to 28V and approaches maximum efficiency at a speed of up to 1.5MHz. Its PWM controller improves system efficiency over analog parts and designed with plateau slope compensation to reduce EMI noise. Additionally, it is equipped with programmable integrated over-temperature protection and over-power protection with hysteretic-based window comparator, enabling adjustable switching threshold. It also includes an integrated over-load protection timer, cycle-by-cycle current limiting and internal soft-start circuits.

Within the AP3407AKTR-G1, an internal clock runs on-the-fly and delivers pulse-width modulation (PWM) signals to gate drivers to regulate the output power. This pulse-width modulation control allows for an adjustable switching frequency and output voltage control. Additionally, the part can also scale output voltage down to 1V and ensures a high power output accuracy of ±0.75%. To make life easier, the IC also provides thermal regulation, over voltage and over current protection, and load line compensation algorithms, ensuring stable and smooth power supply output.
