TPS5103IDBR Description

Short technical summary and product information.

The TPS5103IDBR from Texas Instruments is a synchronous buck DC/DC controller, primarily designed for notebook PC system power applications. This controller supports a wide input voltage range from 4.5V to 25V, with an adjustable output voltage down to 1.2V. It features three user-selectable operation modes: hysteretic mode, fixed-frequency PWM control, or SKIP mode, allowing for optimization between heavy load and light load conditions.

 

The device offers high efficiency up to 95% and a maximum output current of 20A. Key control features include current limit, frequency control, and soft start. The operating temperature range is -40°C to 85°C. The TPS5103IDBR is housed in a 20-SSOP package, suitable for surface mount applications.

 

This controller is designed for step-down (buck) conversion and utilizes synchronous rectification for improved efficiency. It also includes features like standby control and UVLO for internal 5V regulation, contributing to low standby current.
