Overview

The TPS61088RHLR is a high-power density, synchronous boost converter featuring a 10A switch current and an integrated 11-mOhm power switch. It operates over a wide input voltage range of 2.7V to 12V and provides an adjustable output up to 12.6V. This regulator is designed for high efficiency across a broad load range, supporting both PFM and forced PWM modes.

Why Choose This Part

The device offers a programmable switching frequency from 200kHz to 2.2MHz, allowing engineers to optimize for either inductor size or efficiency. Its 10A switch current capability enables high power delivery from low-voltage sources, while the integrated power MOSFETs reduce the external component count and PCB footprint.

Applications

Portable Power Banks
Boosting single-cell Li-ion battery voltages to 5V, 9V, or 12V for fast-charging standards.
Bluetooth Speakers
Providing stable high-power rails for audio amplifiers from varying battery voltages.
Industrial Handheld Terminals
Driving system rails that require high peak currents from a limited input supply.
