DC DC Converters: PQME3-D24-S5-M Application Field and Working Principle

DC/DC converters are one of the most widely used products in the power supply industry due to their ability to efficiently convert electrical power from one voltage level to another. The PQME3-D24-S5-M DC/DC converter is a versatile and highly efficient solution for various applications, from low power system requirements to high power applications. This article will cover the application field and working principle of the PQME3-D24-S5-M DC/DC converter.

Application Field of PQME3-D24-S5-M DC/DC Converter

The PQME3-D24-S5-M DC/DC converter offers an extensive range of applications. The converter is ideal for low power applications such as power supply for TV boxes, LED lighting, medical analyzers, and laptops. It is also suitable for intermediate power applications such as telecommunication, solar systems, home appliances and instrumentation. The 42V to 96V output voltage range of the PQME3-D24-S5-M makes it an excellent choice for high power applications as it is capable of reliably converting input power of up to 300W.

Working Principle of PQME3-D24-S5-M DC/DC Converter

The PQME3-D24-S5-M DC/DC converter is based on a synchronous buck-boost converter topology. The buck-boost converter topology is a combination of the buck and boost converter topologies. It is a highly efficient topology used for voltage conversions involving higher input source and sink voltages. The input voltage is continuously compared to the output, and the duty cycle of the switches is adjusted accordingly. In a buck-boost converter, both the voltage and current are changed.The PQME3-D24-S5-M uses both the buck and boost converter stages in a single package. The buck stage is a pulse width modulation (PWM) circuit that provides a high operating efficiency of up to 99%. It also utilizes low-side transistors in its power circuit to reduce switching losses. The boost stage consists of a quasi-regulated control loop that ports power through a capacitor. The combination of these two stages enables the PQME3-D24-S5-M to tolerate input voltage ranges from 9V to 48V, and output voltage from 42V to 96V.The PQME3-D24-S5-M is also equipped with built-in over-current protection circuits, and soft-start and current limiting features for safe and reliable operation. The current limiting can be adjusted via an external voltage divider, and the total output power can be easily adjusted via the internal current limit setting. This allows the PQME3-D24-S5-M to deliver the output power as required for various applications.

Conclusion

The PQME3-D24-S5-M DC/DC converter offers a highly efficient and versatile power conversion solution. The wide input and output voltage ranges make it an ideal choice for applications from low to high power. The integrated over-current protection and current limiting features provide reliable operation while the adjustable output power settings enable users to customize the output power based on their application.
