| description | The utility model relates to the field of card readers, in particular to a power supply circuit of a fingerprint card reader, which comprises an input power supply, first to seventh capacitors, first to sixth resistors, a first inductor and a power supply chip. By reasonably setting the parameter values of the related components of the power circuit of the fingerprint card reader, a power supply with adaptive parameters and stable output is obtained.
本实用新型涉及读卡器领域，具体涉及一种指纹读卡器的电源电路，包括输入电源、第一至第七电容、第一至第六电阻、第一电感和电源芯片；通过对指纹读卡器的电源电路的相关元器件的参数值进行合理设置，得到参数适配的、输出稳定的供电电源。 |
