DPX6048S05

DC-DC Converters have been around for more than 70 years and are designed to change the electrical characteristics of direct current (DC) electricity. DPX6048S05 is a family of professional DC-DC converters with ultra-wide 36V-60V input range and high up to 95% efficiency. It powers 24V or 48V system from a single 36V or 60V input and meets the most stringent application requirements from IT to television, medical, industrial, automotive, telecommunication, and consumer products. In this article, we will discuss the application field and working principle of the DPX6048S05.

Application Field

Given its 6V-60V wide input range and ±1% load and line regulation, the DPX6048S05 is suitable for industrial applications such as Programmable Logic Controllers (PLCs), Point of Load (PoL) converters, test and measurement equipment, LED Drivers, solar inverters, and other applications. It provides superior power density which is more than twice that of current state-of-the-art solutions and it allows for a more cost-effective solution in various applications.

The DPX6048S05 is a highly integrated 2-step system with a power density of up to 500W/in³. Its input range ensures that it meets the needs of every application from commercial applications such as PLCs to industrial applications such as PoL converters and solar inverters. The module is designed with dual output capability, making it ideal for applications with parallel loads. Additionally, the DPX6048S05 has a simple setup and it is easy to integrate with other systems for a variety of applications.

Working Principle

The working principle of the DPX6048S05 is based on two power stages with intermediate DC link: a buck stage for input regulation, and a boost stage for output regulation. The buck stage provides step-down regulation of the incoming input voltage whereas the boost stage provides step-up regulation of the output voltage. Due to their narrow operating cord range, the two power stages optimize the voltage input and output and make it possible to convert 36V-60V inputs to either 24V or 48V outputs.

In order to maximize efficiency and minimize losses, the DPX6048S05 uses a high-efficiency pulse width modulation (PWM) design with hysteretic current-mode control. This allows for fast and accurate conversion of the input voltage, while ensuring low losses. Additionally, the PWM design also minimizes switching noise and improves the overall power quality.

Moreover, the design is protected against overvoltage, undervoltage, overcurrent, thermal overload, and short circuit. It also features short circuit and overvoltage protection, as well as over-voltage protection for the DC link and over-voltage and under-voltage protection for the output. Additionally, the design has several built-in features such as soft start, adjustable frequency, and external synchronization for maximum control.

In summary, the DPX6048S05 is a highly versatile DC-DC converters well suited for a wide range of industrial applications. It provides superior power density and maximizes efficiency while making it possible to convert 36V-60V inputs to either 24V or 48V outputs. Moreover, it is easy to integrate with other systems and is protected against a variety of hazards.
