TPS54120RGYR Description

Short technical summary and product information.

The TPS54120RGYR from Texas Instruments is a versatile power management IC designed for noise-sensitive applications. It integrates a high-efficiency step-down switching converter with a low-noise, low-dropout regulator (LDO) to deliver quiet power rails.

 

This device supports a wide input voltage range of 4.5 V to 17 V, making it suitable for systems with 12-V power buses. It can provide a continuous output current of up to 1 A. The output voltage is adjustable from 0.8 V to 6.0 V using external resistors.

 

The TPS54120RGYR features a low-noise output of 17 µV RMS from 100 Hz to 1 MHz and can be synchronized to an external clock between 200 kHz and 1.2 MHz. It operates within an ambient temperature range of -40°C to 125°C.

 

Packaged in a compact 24-VQFN (5.5 mm × 3.5 mm) with an exposed pad for improved thermal performance, this component is designed for surface mount applications. Key features include Enable and Power Good signals, and synchronous rectification for enhanced efficiency.
