DC-DC converters are electrical devices which serve the purpose of converting one DC voltage to another. This can be achieved by various means but the most popular form of DC-DC converter is a switching power supply. ULS-3.3/30-D48P-C is a switching power supply based DC-DC converter that has the capacity to step up or down the voltage as required. It is designed to isolate the input and output of a power supply, allowing for different voltage requirements.

Application Field

ULS-3.3/30-D48P-C can be used in a variety of applications due to its wide input and output voltage ranges. It is highly suitable for reliable power supply of mobile devices and other digital products that are driven by a DC supply. In addition, ULS-3.3/30-D48P-C is widely used in the industrial automation, communication, transportation, renewable energy, medical and defense fields. For example, it can be used in automation control systems such as in automated machine tools, industrial robots, and motion control systems.

Working Principle

ULS-3.3/30-D48P-C operates according to the principle of buck-boost topology. In this topology, it can operate both in step-up and step-down modes for a wide range of input and output voltage levels. The ULS-3.3/30-D48P-C uses an integrated circuit integrated with a power MOSFET (metal–oxide–semiconductor field-effect transistor) combined with a synchronous rectifier to regulate the output voltage. It can switch between the two modes quickly, while still keeping the output voltage within the specified range.

When in step-up mode, ULS-3.3/30-D48P-C is connected in a boost circuit. In this mode, the input voltage is lower than the output voltage. This causes the MOSFET to be turned on and the current flowing through it rises rapidly. Therefore, the output voltage is forced to be high. On the other hand, when in step-down mode, the ULS-3.3/30-D48P-C is connected in a buck circuit. In this mode, the input voltage is higher than the output voltage. This causes the MOSFET to be turned off and the current flowing through it declines rapidly. Therefore, the output voltage is lowered.

For over-voltage protection, ULS-3.3/30-D48P-C is equipped with a thermal protection feature. This feature prevents the output voltage from exceeding the rated level in case of an overload. In addition, the impedance control is used to reduce the switching noise by controlling the duty cycle of the switching frequency. This ensures that the noise emissions of the system remain within a certain range.

ULS-3.3/30-D48P-C offers excellent energy efficiency and operational reliability, thus making it an ideal choice for applications requiring precision voltage regulation. Its advanced control circuitry ensures smooth and steady operation even at the lightest of loads which makes it suitable for low power applications such as hand-held medical or communications devices. Furthermore, due to its small size and light weight, ULS-3.3/30-D48P-C is easy to install.
