Working Principle

The LT8616EFE is based on a synchronous boost topology, which uses two power MOSFETs to transfer energy between the input and output stages. In the step-up mode, the input voltage is connected to the source of one power MOSFET and the output is connected to the drain of the other. The internal regulator then works to regulate the output voltage. In the step down mode, the opposite is true and the input is connected to the drain of one power MOSFET and the output is connected to the source of the other. Both power MOSFETs are driven by a PWM signal generated by the internal regulator. The PWM signal controls the on time of both FETs, thus controlling the amount of power transferred from the input to the output.

Conclusion

The LT8616EFE#TRPBF is a promising DC-DC switching regulator IC designed to provide high-performance power solutions to a variety of applications. With its synchronous boost topology, wide input and output voltage range, high efficiency and a wide range of protection features, the LT8616EFE is suitable for a wide range of voltage regulation applications. The device is ideal for use in automotive electronics, industrial, aviation and telecom systems, to provide a reliable, efficient, and cost-effective power solution.
