Evaluation and Demonstration boards and kits provide a bridge from the world of development and design to that of the final product. XR19L210IL40-0B-EB is one such example. This bridge allows for a full understanding of the capabilities of the platform, in this case a 7.5V-60V high input voltage, high DC/DC converter.

The XR19L210IL40-0B-EB features a wide variety of benefits, such as low quiescent current through its converter, excellent value in the form of light weight, low heat, and high efficiency. It can be used in a wide range of applications, including solar panel arrays, LED lighting, and motor driver systems. Its wide input voltage range furthers its usefulness in being able to accommodate lower voltage needs.

In terms of its operation, the XR19L210IL40-0B-EB operates using a primary-side and synchronous rectification with chopper control scheme. This allows it to achieve highest possible efficiency—on the order of 95%, even operating at zero load. Other modes of operation, dual slope, buck, boost, low dropout, and high dropout are also available.

The primary-side and synchronous rectification with chopper control scheme has a few primary advantages over other switching topologies. First, it eliminates the need for an additional switch. This simplifies the system design, which in turn reduces the number of components needed, reduces the amount of hardware involved, and minimizes the board space required to install such an integrated component.

Second, the reduced amount of hardware required also works to minimize switching losses, while the chopper control gives an effective switching frequency control and eliminates switching instability. Finally, the synchronous rectification gives a virtually flat output voltage with little ripple, even at light load.

Also of note, the XR19L210IL40-0B-EB is equipped with the necessary protections to guard against overheat, overcurrent, overvoltage, undervoltage, and other transient conditions. Furthermore, it has a low voltage parasitic design with a maximum current consumption of 3.6µA.

As a simple and utilitarian evaluation and demonstration board, the XR19L210IL40-0B-EB can be used to simulate a wide range of solutions. Its wide acceptance in various fields is only part of its success. Its efficiency, dependability, and reliability are also the main reasons why it is considered to be a good choice for implementing multiple power designs.
