XR79103 - 22V 3A Synchronous Step-Down COT Power Module

General Description

The XR79103 is part of a family of 22V synchronous step-down power modules combining the controller, drivers, inductor, passive components and MOSFETs in a single package for point-of-load supplies.

This module requires very few external components, leading to ease of design and fast time to market.

Key Features

  • including overcurrent, over temperature, short-circuit and UVLO, helps achieve safe operation under abnormal operating conditions. The XR79103 is available in a RoHS-compliant, green / halogen-free space-saving 6mm x 6mm x 4mm QFN package. Typical.

August 17, 2021 XR79103 22V, 3A Synchronous Step-Down COT Power Module Description The XR79103 is part of a family of 22V synchronous step-down power modules combining the controller, drivers, inductor, passive components and MOSFETs in a single package for point-of-load supplies. This module requires very few external components, leading to ease of design and fast time to market. The XR79103 has a load current rating of 3A. 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 XR79103 provides extremely fast line and load transient response using ceramic output capacitors.
