DC to DC converters refer to a type of electronic device that, as it name suggests, converts a direct current (DC) input voltage into a DC output voltage with different value. SPB05C-05 is one of the many DC DC converter products available on the market. It is a non-isolated buck-boost converter with a wide input voltage range, a high power density and excellent performance characteristics.

In terms of application, SPB05C-05 mainly serves battery-powered applications. This DC DC converter can be used to manage all the conversion and voltage regulation needs of a battery-powered system. It is suitable for applications such as power tools, telecom systems, medical and aerospace equipment, and many other appliances that require minimised power losses.

In terms of working principle, SPB05C-05 operates as a non-isolated buck-boost converter. It consists of two power transistors, a primary inductor, a secondary inductor, a filter capacitor and a direction control circuit. When the battery discharges, the two power transistors are operated in buck-mode to efficiently reduce the voltage provided by the battery. When the battery charges, the power transistors are operated in the boost mode to increase the voltage provided by the battery.

In addition, the DC DC converter has an internal MOSFET switch that can disconnect the output voltage and it can also be used as an enable control switch. The output voltage can be adjusted by controlling the duty cycle of the power transistors. The DC DC converter also has built-in protection features such as current limit, thermal overload protection, and short circuit protection to prevent damage to the converter and the connected system.

In conclusion, SPB05C-05 is an effective DC DC converter aimed at managing battery-powered applications. It operates as a non-isolated buck-boost converter with a wide input voltage range, high power density and superior performance. In addition, the DC DC converter has built-in features such as current limit, thermal overload protection, and short circuit protection that help protect the converter and the connected system.
