R12P205S

DC to DC converters are a broad class of power converters which take a DC voltage source at one voltage level and convert it to a DC voltage of higher, lower, or the same level. They can be either non-isolated or isolated DC DC converters. An isolated DC to DC converter is typically used when a DC voltage conversion is needed without disrupting the ground connection of the input power source. The R12P205S is a digital DC to DC converter which is classified as an isolated module.

The R12P205S is a synchronous switching buck module designed for use in isolated DC DC converter applications. It is a digitally tunable DC DC converter and an excellent choice for applications requiring up to 30W of output power. This module supports a wide input voltage range of 4.5V to 14V and provides up to 12V of adjustable output voltage. It has a wide temperature range operation from -40°C to 85°C and is packaged in a compact and efficient SIP-8 (Single In Line-8) form factor.

The R12P205S works as a buck converter, where the input voltage is stepped down by a factor. To accomplish this, the R12P205S takes DC voltage input and sends it through two power MOSFETs controlled through a PWM signal. This PWM signal is generated by a control circuit. The MOSFETs alternately draw and release power from the input voltage to create a pass-through current, thus controlling the output voltage. Since the PWM signal is digitally generated and adjustable, the output voltage can be precisely adjusted.

The module also includes undervoltage and overvoltage protection circuits to ensure that the output voltage does not exceed the specified level and protects the module from any voltage fluctuations in the input voltage. In addition, the module has foldback current limiting and short-circuit protection to protect the load connected to the module from any overload conditions.

The R12P205S DC to DC converter is a great choice when an isolated solution is needed, and near constant output voltage is required. It is suitable for applications such as industrial equipment, PoE (Power over Ethernet) applications, and other applications that require efficiency, reliability, and excellent performance.
