TPS55289RYQR TI Voltage Regulators - DC DC Switching Regulators
The TPS55289RYQR is a synchronous buck-boost converter with integrated FETs and I²C interface, operating from a 3-V to 30-V input and providing an adjustable output from 0.8-V to 22-V, delivering up to 8-A output current . It features programmable switching frequency from 200 kHz to 2.2 MHz, spread spectrum for EMI mitigation, and includes output voltage margining, current limit, and dynamic voltage scaling via I²C . The device provides high efficiency across the full load range with automatic mode transition. Packaged in a 21-pin VQFN-HR (RYQ) (3 mm × 5 mm), this converter is ideal for USB Power Delivery (PD) applications, battery-powered equipment, and industrial power supplies requiring wide input voltage range and adjustable output.
