DC DC Converter - SPM1004-0V8C Application Field and Working Principle

DC DC converters are widely used in various kinds of electronic applications, such as power supply and UPS\'s, automotive and aerospace applications, telecommunications, lighting systems, medical equipments, etc. They are the most efficient way to efficiently transfer electrical power between two different power levels or voltage supplies. Judging from different power requests, DC DC converters are divided into different types according to their characteristic and application field.SPM1004-0V8C is a type of DC DC converter that is used in powersupply and UPS applications. It is an Open Frame design module, designed to convert a higher input voltage down to a lower output voltage for use in power supplies, safeguards, motor- vehicle audio power amplifiers and any other application, where a step-down volt converters are needed.The working principle of the SPM1004-0V8C DC DC converters is quite simple. It converts input voltage to a lower voltage, and is capable of reducing the output voltage up to 0.5V. The primary function of this type of DC DC converter is to reduce the level of the input voltage and to regulate current output while maintaining the safe operation of the power supply or UPS.The SPM1004-0V8C employs a Buck converter circuit in its operating system to control the flow of current. The Buck converter works, however, by lowering the input voltage to a lower level and then regulating it in order to maintain a constant output voltage. This regulation process is done through feedback signals obtained from the output voltage of the converter. When the output voltage is lower than the required voltage, the feedback signal turns the switch of the converter on in order to increase the output voltage, whereas in the opposite case, when the output voltage is higher than the required voltage, the feedback signal turns the switch of the converter off in order to reduce the output voltage back to the required level.The salient features of the SPM1004-0V8C DC DC converter include: a wide operating input voltage (4~14V); converter efficiency up to 96%; peak current up to 3A; good like / short circuit protection, over-temperature protection & overload protection; low ripple noise; high switching frequency (kHz); and low EMI & RFI effect.In conclusion, the SPM1004-0V8C DC DC converters is suitable for powersupply and UPS applications, because of their high efficiency, low ripple noise, and low EMI & RFI effects. Moreover, it makes use of the Buck circuit, which is a reliable and simple solution to reduce and regulate output voltage.
