Overview

The TPS63070RNMR is a high-efficiency buck-boost switching regulator designed to provide a stable 2.5V to 9V output from an input voltage range of 2V to 16V. It features an automatic transition between buck and boost modes, ensuring seamless regulation even when the input voltage fluctuates above or below the target output. With a 2A output current capability and a high 2.4MHz switching frequency, it allows for the use of small external components in space-constrained designs.

Why Choose This Part

The device offers a very low quiescent current of 50uA and a shutdown current of 12uA, making it ideal for battery-operated devices requiring long standby times. Its high 2.4MHz switching frequency reduces the footprint of inductors and capacitors, while integrated features like Power Good and overtemperature protection simplify system-level design.

Applications

Single or Multi-cell Li-Ion Battery Power
Maintains a constant output voltage as the battery discharges from 4.2V down to its cutoff, bridging the gap between buck and boost requirements.
Industrial Low-Power Systems
Regulates 12V industrial rails down to 3.3V or 5V logic levels with high efficiency and robust protection features.
USB Power Delivery Ports
Provides stable power for peripherals that require precise voltage regulation from varying USB input sources.

Getting Started

To evaluate the IC, designers typically use the TPS63070EVM-693 evaluation module, which provides a reference layout for the 15-pin VQFN package. When designing the PCB, keep the power loops short and place the input and output capacitors as close as possible to the PGND and VIN/VOUT pins to minimize EMI and voltage spikes.
