DC-DC converters are electronic devices that are capable of converting a direct current (DC) voltage or power level from one value to another. The DC-DC converter under discussion here is the AEE04F36-LS. It is an integrated switching regulator that combines the power MOSFET switch, the control logic and current sensing circuit to form a low profile, single-chip device. It is designed to regulate output voltage from 1.2 to 36V. Its non-isolated, synchronized switch mode power converter has full protection features and enhanced EMI performance.

AEE04F36-LS Application Field

The AEE04F36-LS DC-DC converter is designed to reduce electrical noise and improve energy efficiency. It is commonly used for a variety of applications, including motor control, robotics, Automotive, industrial, and medical equipment. It is specifically designed for applications with non-standard DC input voltage, such as automotive and solar. It is ideal for applications that require an adjustable voltage output such as in ride-on vehicles, drones, industrial control systems, and medical equipment. Its enhanced EMI and protection features make it an excellent choice for RF, switching, and power amplification applications.

AEE04F36-LS Working Principle

The AEE04F36-LS DC-DC converter is based on a switching buck-boost regulator. The device consists of a high-side MOSFET switch connected to an inductor and a low-side MOSFET switch connected to a diode. The MOSFET switches are driven by the internal current-mode control logic based on a dedicated oscillator. When power is applied, the control logic starts to transition the high-side switch from off to on, and, simultaneously, the low-side switch transitions from on to off. This causes the inductor to store energy, which is later released when the switch transitions back to the off state. The output voltage is regulated by controlling the on and off time of the switches, which is determined by the external reference pin. For over current protection, the AEE04F36-LS also includes a current limit and a thermal shutdown feature.

Conclusion

The AEE04F36-LS is a DC-DC converter designed for applications with non-standard input voltage. It has a wide adjustable voltage range from 1.2 - 36V, making it suitable for a wide range of applications. It is based on a switching buck-boost regulator and includes full protection features and enhanced EMI performance. This makes it an excellent choice for motor control, robotics, Automotive, industrial, and medical applications.
