DC-DC converters are a significant part of power supplies used in a variety of applications. DC-DC converters use voltage and current regulation techniques in order to convert an input voltage into a desired output voltage. In a DC-DC converter, the output voltage can be adjusted by changing the input voltage, as well as by using other methods such as pulse-width modulation (PWM), buck-boost, and slope compensation. The PV1R5245 is a unique DC-DC converter that can convert a 12V input into any output voltage within the range of 1.2V to 5.2V with adjustment resolution of just 0.01V.

Application Field

The PV1R5245 is particularly suitable when an adjustable output voltage is needed. With the adjustable resolution and wide output voltage range, the PV1R5245 is suitable for a wide variety of applications. Examples include automotive, telecommunications, computer and consumer electronic devices, as well as industrial and medical equipment. It is also suitable for applications where the input voltage varies, as the output voltage can be adjusted with precision. In addition, the PV1R5245 is also suitable for applications which require ultra-high efficiency as the converter there is capability of performing up to 15A output current with an efficiency of 95%.

Working Principle

The PV1R5245 is a non-inverting (NC) buck-boost DC/DC converter with an adjustable output voltage. As its name implies, the PV1R5245 is capable of regulating input voltage levels within a range of 1.2V to 5.2V. The input voltage is converted into an adjustable output voltage by using Pulse Width Modulation (PWM) and switching a Power MOS device on and off in decreasing and increasing currents respectively. To maintain the desired output voltage, the frequency of the input pulse is adjusted by a microcontroller. Furthermore, the output voltage is also controlled by adjusting resistors, allowing for a precise output voltage adjustment.

Conclusion

The PV1R5245 is a unique DC-DC converter that is capable of converting a 12V input into any output voltage within the range of 1.2V to 5.2V, with an adjustable resolution of only 0.01V. It is suitable for a wide range of applications in automotive, telecommunications, computer and consumer electronics, as well as in industrial and medical equipment. Furthermore, its built-in PWM switching and adjustable resistor output provide for an ultra-high efficiency of up to 95%, making it the ideal choice for the most demanding power control applications.
