MaxLinear, Inc. Voltage Regulators - DC DC Switching Regulators XR76117ELMTR-F

The XR76117ELMTR-F is a synchronous step-down voltage regulator designed for point-of-load applications, capable of delivering up to 15A of load current. It operates within a wide input voltage range of 5V to 22V, making it suitable for standard power rails such as 5V, 12V, and 19.6V. The device utilizes a proprietary emulated current mode constant on-time control scheme, which allows for rapid line and load transient response while eliminating the need for loop compensation, thus simplifying circuit design. This regulator supports a selectable power-saving mode that enhances efficiency during light load conditions by enabling discontinuous mode operation. It features robust protection mechanisms, including overcurrent, overtemperature, overvoltage, short-circuit, and undervoltage lockout (UVLO), ensuring safe operation under various conditions. The XR76117 is housed in a compact 5mm x 6mm QFN package and is compliant with RoHS standards, making it a suitable choice for applications in servers, distributed power architectures, and various digital signal processing supplies.
