Overview

The TPS63070 is a high-efficiency buck-boost converter designed to provide a stable output voltage from input sources that can be higher or lower than the target rail. It supports a wide input voltage range of 2V to 16V and delivers up to 2A of output current, making it ideal for systems powered by multi-cell batteries or unregulated wall adapters.

Why Choose This Part

The device features a high 2.4MHz switching frequency which allows for the use of small surface-mount inductors and capacitors. It offers an ultra-low quiescent current of 50uA and a power-save mode to maintain high efficiency during light-load conditions, while the integrated VSEL pin enables dynamic voltage scaling.

Applications

Multi-cell Li-ion Battery Power
Efficiently regulates a 2.5V to 9V output from 2S or 3S Li-ion configurations throughout the entire discharge cycle.
Industrial Rail Stabilization
Provides a steady power rail for sensors and controllers in systems with varying 12V bus voltages.
USB Power Delivery
Manages voltage conversion for USB-C applications where input voltages may fluctuate between 5V and 15V.
Point-of-Load Regulation
Acts as a high-efficiency intermediate stage for distributed power architectures requiring up to 2A.

Getting Started

Engineers should evaluate the part using the TPS63070EVM-693 evaluation module to test transient response and thermal performance. Ensure that the input and output capacitors are placed as close as possible to the VQFN package pins to minimize parasitic inductance and switching noise.
