Introduction

DC-DC converters are electrical systems that convert the input direct current (DC) signal into a second output DC signal with a desired voltage and current properties. As the current and voltage sources for all kinds of electronic devices, DC-DC converters come in several variants, depending on their specific uses and specifications. One such variant is CBS3502448-T, a step-down buck-type DC-DC converter module.

Application Field

CBS3502448-T features high efficiency up to 95.9%, a minimum operating temperature of -40 degrees Celsius, and a continuous current rating of 4.6A (with a peak current of 8A). This makes it ideal for automotive applications, where superior thermal management capability is required. Additionally, it is often employed in various industrial settings, such as photovoltaic systems and electronic equipment, where reliable, high-density DC supply is needed.

Working Principle

The CBS3502448-T converter module employs a buck-type DC-DC conversion technology, which allows it to input Vcc input voltage from 5V to 24V and to switch the output voltage to the desired level. More specifically, the converted voltage is proportional to the duty ratio of the switching cycle. To create this switching cycle the module relies on an internal Pulse Width Modulation (PWM) controller, which contains a MOSFET driver that regulates the power draw from the input. The MOSFET is connected to a control circuit, which builds up the switching cycles, following linear or non-linear functions of the input voltage. Additionally, the module also has a stable output voltage range which can be programmed with a voltage setting potentiometer. As for its power loss, the CBS3502448-T has a built-in thermal protection function that can help regulate the power output and maintain system stability, ensuring that the desired output voltage range is maintained.

Conclusion

In conclusion, the CBS3502448-T is a reliable and efficient buck-type DC-DC converter module that meets the demands of modern electronic applications. It features high efficiency of 95.9%, a continuous current rating of 4.6A, and a wide operating temperature range of -40 to 85 degrees Celsius. The module’s internal PWM controller and MOSFET driver also help maintain stable system performance, while its built-in thermal protection function helps regulate the power output. This makes it an ideal choice for automotive and industrial applications.
