The RDK-420 is an evaluation board designed for off-line SMPS applications. It is a complete AC/DC and DC/DC power converter solution for both high-power and low-power applications. The RDK-420 supports two output voltages, one of which is adjustable via a potentiometer. It has a number of protective features including short-circuit and thermal protection.

The RDK-420 is based on the IR3525 and IR108 are high performance analog PWM controllers. These devices are designed to provide extremely efficient, low EMI, and highly reliable power conversion. The RDK-420 also has many features that make it suitable for a variety of power supply applications such as medical, industrial, automotive, and consumer.

The RDK-420 includes the IR3525 for the rectifier and IR108 for the inverter. The IR3525 can be used for both Boost and Flyback applications. The rectifier section is powered by a single FET in either a synchronous rectifier topology or a full-wave bridge rectifier. The rectifier section supports up to 30V DC or 24V AC inputs. The IR108 can be used as either a Buck or Boost converter, and is capable of operating from a wide input voltage range of up to 80V DC.

The output voltage of the RDK-420 is adjustable via the onboard potentiometer. The output voltage range is dependent on the transformer turns ratio and the input voltage. The RDK-420 has several protective features, including short-circuit protection, over-temperature protection, and overcurrent protection. Additionally, the RDK-420 supports current and voltage programming.

The RDK-420 is designed to be flexible and configurable in order to meet the needs of a variety of applications. It can be used in grid-connected applications, standalone applications, and in applications that require high power. Additionally, the RDK-420 can be used for both AC and DC power distribution and energy storage.

In summary, the RDK-420 evaluation board is an ideal solution for off-line SMPS applications. It is based on two high performance PWM controllers, the IR3525 and the IR108. The board supports a variety of input voltages, and the output voltage can be adjusted with the onboard potentiometer. Furthermore, the RDK-420 includes a number of protective features and supports current and voltage programming. As such, it is a highly reliable solution for many power conversion applications.
