SPU03N-05

DC-DC Converters provide the essential transformation of voltage, current or power needed to create stable power supplies that are able to meet the specific requirements of the devices they power. The SPU03N-05 is one such converter, that is used in a variety of applications such as industrial automation, automotive, consumer electronics and aerospace.

The SPU03N-05 is a non-isolated buck (STEP-DOWN) DC-DC converter that can take an input of 4.5-14 VDC and output 3.3 VDC with a peak current of up to 3A. It features an integrated high side MOSFET, an integrated current sense resistor and a high efficiency synchronous rectification controller. This allows for an efficient, rugged and cost-effective solution for DC-DC conversion.

The working principle of the SPU03N-05 is based on the buck converter topology. When operating in buck mode, the inductor stores energy when the switch is closed, and then releases the energy when the switch turns off. This allows for a decrease in output voltage while maintaining a constant output current. The input voltage, output voltage and output current are controlled through the use of feedback loops from the output of the SPU03N-05.

The SPU03N-05 is suitable for a wide range of applications, such as automotive, industrial, consumer electronics, telecommunication, medical, aerospace and defense. It is capable of providing a low cost solution for the reliable power supply of microcontrollers, memory and other logic circuits. In addition, it supports wide temperature range operation from –40°C to 105°C due to its internal thermal protection.

In summary, the SPU03N-05 DC-DC converter is designed to provide an efficient and cost-effective solution for the reliable power supply of a wide variety of applications. It features an integrated high side MOSFET, an integrated current sense resistor, and a high efficiency synchronous rectification controller, which allows for a low cost solution with a wide temperature range operational capability.
