The power conversion efficiency of these three products is as high as 90 to 93%, and the maximum output current is 3A. The input voltage and output voltage are as follows:
The input voltage of the FPDK12S1R003PA is +8.0 to 14.0V, and the output voltage is +1.0 to 6.6V.
The input voltage of the FPDK05S1R003PA is +3.0 to 6.0V and the output voltage is +1.0 to 3.63V.
The input voltage of the FPDK05S1R003PAV is +4.5 to 5.5V and the output voltage is +1.0 to 3.63V.
The output voltage is adjusted by external components.
Protection functions such as overvoltage current protection and overheat protection, as well as remote ON/OFF functions. In addition, it also meets the safety requirements of the information processing equipment UL60950 and IEC/EN60950 adopted in Europe and the United States. The working temperature is -40 ~ +85 °C.
FDK has developed a small non-isolated DC-DC converter "DK" series, which is smaller than the original product with an output current of 3A. Miniaturization is achieved by improving the power supply circuit and high-density packaging technology. This time, we will introduce three products, "FPDK12S1R003PA", "FPDK05S1R003PA" and "FPDK05S1R003PAV", which have different input voltage ranges. They are SMD (surface-mounted device) type for surface packaging, and the external dimensions are 16.7 mm × 8.9 mm × 3.4 mm. Compared with a power supply circuit composed of a single component, development time can be shortened and package area can be reduced. Imagine being equipped in communication devices such as routers and servers.
