TPS51220ARSNR Description

Short technical summary and product information.

The TPS51220ARSNR from Texas Instruments is a high-performance synchronous buck controller. It is engineered for notebook system power and point-of-load applications, offering a wide input voltage range from 4.5V to 32V and supporting output voltages from 1V to 12V.

 

This controller features a fixed-frequency PWM operation with a selectable 200-kHz to 1-MHz frequency. It supports D-CAP and current mode control, providing flexibility for various design requirements. Key electrical characteristics include a maximum output current of 20A, a typical quiescent current of 0.0013A, and a maximum duty cycle of 99%.

 

The TPS51220ARSNR is housed in a QFN-32 package and is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C. The controller includes features such as selectable light load operation, programmable droop compensation, and adjustable soft start.

 

Protective features include Overcurrent Limit (OCL), Overvoltage Protection (OVP), Undervoltage Protection (UVP), and Undervoltage Lockout (UVLO), with an option to disable OVP. It also incorporates thermal shutdown and an output discharge function, which can also be disabled.
