DC/DC converters are essential electronic components used to safely convert direct current (DC) power from one voltage to another. The XCL221B251ER-G is a highly efficient, light-weight buck converter, designed to regulate and convert a DC input voltage of up to 36V into an adjustable voltage of 1.2V to 28V DC output. Its diminutive size makes it suitable for demanding applications in space-constrained systems. This compact size also results in a high level of efficiency, which helps reduce system costs and minimize waste heat. With its very low output ripple current, this converter offers excellent transient protection for loads ranging from 3A to 15A.

The XCL221B251ER-G employs a step down power conversion topology, enables efficient, regulated conversion of a wide input voltage range, while simultaneously operating either in pulse width modulation (PWM) or pulse frequency modulation (PFM) mode. It is ideally suited for applications in which the voltage needs to be ramped up or down when turned on or turned off. The device comes with a number of safety features, such as over-current (OCP) protection, over-voltage protection (OVP) and thermal protection (OTP) to keep the device and connected circuits safe in adverse conditions.

In terms of inputs, the XCL221B251ER-G is designed to accept DC power from a wide range of sources, such as batteries, solar panels, and power adapters. For output, it can supply a precise output voltage ranging from 1.2V to 28V DC depending on the application needs. It can be used in applications such as automotive, industrial, and medical electronics, as well as in various other alternatives, such as communications, consumer electronics, office automation, and other general purpose power solutions.

The XCL221B251ER-G utilizes advanced synchronous rectification technology to significantly reduce component count. This technology helps reduce costs and increase efficiency as well as reducing external component count. Its external integrated circuit (IC) integrated design is also designed with a wide temperature range for extended reliability and long-term stability.

To optimize the operation of the XCL221B251ER-G, the integrated MOSFETs is configured specifically for high-performance switching and robust current handling. The device is also designed to run quieter, increasing the power supply\'s reliability and reducing the risk of distress to connected components. Moreover, its high level of efficiency enables a low overall cost of ownership.

Housed in an SOP8 package and compliant with IEC/EN60950, the XCL221B251ER-G offers excellent EMC performance. Its ground pin connected to the metal plating ensures protection against electric shocks, creating a safe, reliable system for any application. The XCL221B251ER-G is compatible with a wide variety of DC power sources, allowing engineers to design power supplies for nearly any application.
