DC DC Converters

DC DC converters are widely used devices that are engineered to convert direct current (DC) from one voltage level to another. As part of the larger categories of switch-mode power supplies (SMPS) or DC/DC converters, DC/DC converters are widely used in many industrial applications from the processing of consumer goods to large scale energy needs. One such type of DC/DC converter is the EXQ125-48S3V3.

EXQ125-48S3V3 Application Field and Working Principle

The EXQ125-48S3V3 is a isolated intermediate DC/DC converter module that is designed to work with inputs ranging from 9 to 18 volts, and can be used to provide isolated outputs as high as 48 V. It is widely used in multiple applications from communications to instrumentation and automotive. Specifically, the EXQ125-48S3V3 is a great fit for distributing power to transmitting components and for post regulator systems.

The EXQ125-48S3V3 DC/DC converter module has a number of features that distinguishes it from other DC/DC converters. Firstly, it boasts an excellent efficiency of over 90%, significantly lower power loss and low temperature rise due to the synchronous rectification, FR4 card design, and design of its power source. It also offers isolation, soft start function, built-in EMI filters, electrolytic capacitors, protection functions, wide input and output voltage range, and anti-reverse connection functions.

The EXQ125-48S3V3 also offers voltage adjustability, allowing both the voltage level and impedance to be externally adjusted with something called sense resistors. This helps to keep the output voltage of the EXQ125-48S3V3 to the desired level when input to output ratio fluctuations occur.

The working principle of the EXQ125-48S3V3 converter is relatively straight-forward. The device consists of two main components: a transformer and an active circuit. When the input voltage is connected to the active circuit, it is then transferred to the transformer, which is then divided into two different voltages. After the voltage is divided, the output voltage is obtained after rectification and filtering. The circuitry of the EXQ125-48S3V3 also includes components such as logic devices, H bridges, emitter-follower solutions, and integrated circuits.

All in all, the EXQ125-48S3V3 DC/DC converter module is designed to meet the requirements of a variety of applications that need the delivery of a highly reliable, efficient, and stable output voltage. Whether it’s used in consumer goods, automotive applications, or large scale energy applications, the EXQ125-48S3V3 is a great go-to device for DC/DC converter needs.
