The Texas Instruments TPS55289RYQR is a versatile synchronous buck-boost converter designed for efficient power supply rail conversion. It supports a wide input voltage range from 3V to 30V and provides a programmable output voltage from 0.8V to 22V with 10mV steps, making it ideal for USB Power Delivery (USB PD) applications.
This converter integrates four MOSFET switches and features an I2C interface for control and monitoring. It boasts high efficiency, reaching up to 96% at 12V input and 20V output with 3A load. The switching frequency is programmable from 200 kHz to 2.2 MHz, with options for clock synchronization and spread spectrum to mitigate EMI.
Protection features include output overvoltage protection, hiccup mode for short-circuit protection, thermal shutdown, and an 8-A average inductor current limit. The TPS55289RYQR is available in a compact 3.0-mm × 5.0-mm VQFN-HR package, suitable for space-constrained designs.
Key applications include wireless chargers, USB PD power supplies, docking stations, industrial PCs, power banks, and monitors.
