DC DC Converters

DC-DC converters are electrical components used to convert one electrical voltage to another. DC-DC converters are widely used in a variety of industries for power supply voltage conversion and are typically used as a regulated voltage source in applications such as telecommunications systems, automotive power systems, medical equipment, military avionics, process control, aerospace systems, and other industrial or commercial applications. The LTM8025IY#PBF is one type of DC/DC converters specifically designed for a variety of purposes such as DC/DC voltage-conversion, voltage-regulation, wave-shaping, and signal-processing applications. This article will discuss the application fields and working principle of the LTM8025IY#PBF.

Application Field

The LTM8025IY#PBF is a synchronous monolithic DC-DC buck-boost converter module with integrated high side and low side FETs, adjustable output voltage, wide input voltage range, high efficiency, integrated EMI/RFI filtering, and ultra-low quiescent current. This converter is ideal for applications that require a wide input voltage range with adjustable output voltage capability and high efficiency with EMI/RFI filtration. Some common applications for the LTM8025IY#PBF include power systems for telecom, industrial, medical, consumer, military and aerospace systems, DC/DC voltage conversion for data acquisition systems, and voltage regulation for multi-source power systems.

Working Principle

The LTM8025IY#PBF works by converting a DC input voltage to a DC output voltage. The device consists of a high side and low side FET, the input voltage source, the output voltage, and the control circuitry. The high side FET is connected to the input voltage source and the low side FET is connected to the output voltage. This device works by switching the high side FET on and off at a certain frequency and varying the duty cycle in order to regulate the output voltage. The control circuitry also adjusts the gate delay and output current limit in order to protect the device from overload and short-circuit conditions.The IC includes several features that improve performance, such as input and output filters that reduce EMI/RFI noise, frequency foldback, internal synchronous rectification for higher efficiency, and adaptive dead time. The low quiescent current mode reduces power consumption when load currents are low. Additionally, the IC includes under-voltage lockout and input UVLO protection that guarantee the device stays enabled only if the input voltage is within the specified range.

Conclusion

The LTM8025IY#PBF is a DC-DC converter module with a wide input voltage range, adjustable output voltage, and high efficiency with EMI/RFI filtration. This module is ideal for a variety of applications such as power systems, voltage conversion, and voltage regulation. The device works by switching the high side FET on and off and varying the duty cycle to regulate the output voltage. The device also has several features such as filters and protection that improve performance and efficiency.
