TPS552872RYQR TI Buck-Boost Converter | 21-VQFN-HR(3X5) | 36V, 2.2MHz

Product Overview

The TPS552872RYQR is a high-performance, synchronous buck-boost converter from Texas Instruments, designed to provide a regulated output voltage from input sources that can be above, below, or equal to the output. It operates over a wide input voltage range of 2.7V to 36V and delivers up to 3A continuous output current. The device integrates four low RDS(on) power MOSFETs and uses a fixed-frequency, peak-current-mode control architecture for excellent line and load regulation. Housed in a compact 21-pin VQFN-HR (3mm x 5mm) package, it is ideal for space-constrained applications requiring high efficiency and flexibility.
