DC-DC converters are used to convert one form of power into another. In the case of PCM1-S5-S5-SA application field and working principle, a DC-DC converter is used to convert low direct current (DC) power from one source to the higher voltage required by the device being operated. This type of converter is used to provide reliable, cost-effective power in numerous applications including automobiles, aircraft, medical and industrial electronics, office automation and communications equipment, among others.

The PCM1-S5-S5-SA version of the converter is designed for use in medium- to high-power applications with input voltages ranging from 4.5 to 30 Volts DC, and output voltages of 18 Volts DC or higher. The converter can also accommodate high frequency switching of up to 50kHz.

The PCM1-S5-S5-SA converter achieves its power conversion through a synchronous buck-type DC/DC converter. The synchronous buck circuit consists of two main components: an inductor and a MOSFET switch. The inductor acts as a storage device, with energy being alternately drawn from the input voltage source and released to the output circuit. The MOSFET switch acts as a switch, transferring the stored energy from the input voltage to the output circuit.

The converter’s operation begins with the MOSFET switch closed, allowing the current to ramp up in the input circuit. As it reaches a predefined peak level, the MOSFET switch is opened, interrupting current flow in the input circuit. This action causes current stored in the inductor to be discharged into the output circuit, thereby generating the desired output voltage.

The key to proper execution of this process lies in the precise synchronization between the control circuit and the MOSFET switch. If the switch is opened or closed too soon or too late, it can cause instability, resulting in lower than expected efficiency, poor power quality or lack of regulation. To ensure accurate synchronization, the regulator circuit is typically fed a timing signal from the input voltage source.

The PCM1-S5-S5-SA converter is designed to provide an accurate, reliable and cost-effective way to convert DC power for numerous applications. Its synchronous buck-type DC/DC conversion allows it to handle a wide range of input voltages and frequencies, while maintaining a high level of efficiency. In addition, its precise control circuit ensures accurate synchronization of the MOSFET switch for optimal power conversion performance.
