XRP6141 - 35A Synchronous Step Down COT Controller

General Description

The XRP6141 is a synchronous step-down controller for point-of load supplies up to 35A.

A wide 4.5V to 22V input voltage range allows for single supply operation from industry standard 5V, 12V and 19.6V rails.

Key Features

  • including overcurrent, over-temperature, short-circuit and UVLO, help achieve safe operation under abnormal operating conditions. The XRP6141 is available in RoHS compliant, green/halogen free space-saving 16-pin 3x3 QFN package. Rev. 2.0.0.

XRP6141 35A Synchronous Step Down COT Controller July 2015 GENERAL DESCRIPTION The XRP6141 is a synchronous step-down controller for point-of load supplies up to 35A. A wide 4.5V to 22V input voltage range allows for single supply operation from industry standard 5V, 12V and 19.6V rails. With a proprietary emulated current mode Constant On-Time (COT) control scheme, the XRP6141 provides extremely fast line and load transient response using ceramic output capacitors. It requires no loop compensation hence simplifying circuit implementation and reducing overall component count. The control loop also provides exceptional line regulation and maintains constant operating frequency.
