TPS53319DQPR Description

Short technical summary and product information.

The Texas Instruments TPS53319DQPR is a high-efficiency, 14A synchronous buck converter designed for space-conscious power systems. It operates with a conversion input voltage range of 1.5 V to 22 V and a VDD input voltage range of 4.5 V to 25 V, providing an adjustable output voltage from 0.6 V to 5.5 V.

 

This device integrates power MOSFETs and supports a continuous output current of up to 14A. It offers a selectable switching frequency from 250 kHz to 1 MHz, allowing for optimization of component size and performance. The TPS53319DQPR also features Auto-Skip Eco-mode for light-load efficiency and a shutdown current of less than 110 µA.

 

Packaged in a 22-pin LSON-CLIP (6x5) surface-mount configuration, this buck converter is suitable for applications requiring high current density and efficiency. Its design emphasizes ease of use and a low external component count, making it a versatile solution for various power management needs.
