The XR79106EVB has been engineered to provide an off-line SMPS solution for evaluation and development. It allows users to prototype and evaluate the performance and power efficiency of their designs, under a variety of load and temperature conditions. The XR79106EVB utilizes its simplistic design to provide an industry-standard solution, while also maintaining a level of portability and flexibility that allows it to be used by a wide range of applications. This includes applications in consumer, industrial, and medical electronics.

The XR79106EVB is based on the XR79106 integrated circuit, which is a special type of off-line DC/DC converter commonly found in applications such as air conditioners, refrigerators, and security cameras. The XR79106 features an efficient closed-loop voltage mode control loop, which ensures accurate operation for a wide range of loads and ambient temperatures. It operates from an input voltage range of 10 – 36V, and provides an output voltage ranging from 0.9 – 25V with up to 300mA of output current. The XR79106EVB provides the flexibility of multiple power supply modes (controlled by the switch SW1), which can produce either a Fixed Output Voltage (FOV) or a Fixed Output Current (FOC) for accurate evaluation. It also features an on/off control pin, which can be used for power sequencing and protecting the load from any unexpected power failure.

The XR79106EVB also provides protection features that are usually not available with off-line DC/DC converters. These include self-reset protection for Under Voltage Lock Out (UVLO) and Over Voltage Lock Out (OVLO), built-in current limit and short-circuit protection, and over-temperature protection. All these features ensure a safe and reliable operation even under extreme conditions, while also providing a high power efficiency. Other features that make the XR79106EVB an attractive device is the small footprint (6.3 cm x 9.1 cm) and low component count, which makes it very easy to assemble and integrate. Additionally, the XR79106EVB features an adjustable output voltage setting by means of the potentiometer VR1, which provides an analog voltage scaling function.

The XR79106EVB is an ideal choice for development and evaluation of switch mode power supplies, with its capability to provide highly accurate power control across various loads and range of temperatures. It allows designers to confidently prototype and verify the performance of their designs, and its small footprint and low component count make it a great choice for quick integration into a variety of applications. The XR79106EVB is easily programmable with its integration of the XR79106 controller, and its protection features will ensure reliable operation even under extreme conditions.
