TPS55289-Q1 Buck-Boost Converter Evaluation Module
Description
The TPS55289-Q1 integrates four MOSFETs
providing a compact design for a variety of
applications and is optimized for converting battery
voltage into power supply rails. Through the I
interface, the output voltage can be programmed
from 0.8V to 22 V with 10 mV step and the output
current limit is programmable up to 6.35A with 50
mA step, which is a good choice for USB Power
Delivery (USB PD) applications. The TPS55289-
Q1 has adjustable external loop compensation,
programmable switching frequency, optional spread
spectrum and rich protection features. All these
features bring flexibility and design optimization for
overall performance, as well as BOM optimization and
design cost.
Get Started
1. Order the EVM at ti.com.
2. Read the user's guide carefully.
3. Prepare the bench setup per instructions. Take
precautions to prevent damage by ESD when
handling the EVM.
4. Power up the EVM by following the recommended
steps.
5. Run tests and measurements. Take cautions of
high voltage and hot temperature produced by the
EVM during test.
