TPS51220ARSNR Description

Short technical summary and product information.

The Texas Instruments TPS51220ARSNR is a fixed-frequency, peak current-mode buck controller. It is designed for notebook system power applications and offers a wide input voltage range from 4.5V to 32V, with an adjustable output voltage from 1V to 12V.

 

Key electrical specifications include a maximum output current of 20A and a typical quiescent current of 1.3mA. The controller features a high duty cycle of up to 99% and operates with a selectable frequency between 200kHz and 1MHz. It supports D-CAP and current mode control architectures.

 

This controller is available in a QFN-32 package, specifically WQFN (RTV) measuring 5mm x 5mm and WQFN (RSN) measuring 4mm x 4mm. It is designed for surface mount applications and operates within an ambient temperature range of -40°C to 85°C. The device includes features such as selectable light-load operation, programmable droop compensation, and adjustable soft start.

 

Applications for the TPS51220ARSNR include notebook computer systems, I/O bus power, and point-of-load applications in LCD TVs and MFPs. It provides essential protections like OCL/OVP/UVP/UVLO and thermal shutdown.
