TPS61089RNRR - 7A Synchronous Boost Switching Regulator IC, 2.7V–12V Input, VFQFN-11 Package

The TPS61089RNRR from Texas Instruments is a high-efficiency 7A synchronous boost converter designed for portable, battery-powered, and high-performance electronic systems. Featuring an integrated 19mΩ main power switch and 27mohm rectifier switch, it provides excellent efficiency and compact design. Operating from a wide 2.7V to 12V input range, the device supports output voltages up to 12.6V, making it ideal for applications powered by single-cell or dual-cell Li-ion batteries.

The TPS61089 uses an adaptive constant off-time peak current control topology, ensuring fast transient response and stable regulation. It automatically switches between PWM mode under medium to heavy loads and PFM mode during light loads to optimize efficiency. The TPS610891 variant operates solely in PWM mode, avoiding issues caused by low-frequency switching. The device supports adjustable switching frequencies from 200kHz to 2.2MHz, providing flexibility in efficiency and size optimization. Built-in features include a 4ms soft start, adjustable peak current limit, 13.2V output overvoltage protection, cycle-by-cycle overcurrent protection, and thermal shutdown, ensuring reliable and safe operation. Housed in a compact VFQFN-11 package, this IC is engineered for high-density power designs in portable and industrial systems.

Key Features:

  • Wide Input Voltage Range: Operates from 2.7V to 12V, suitable for single or dual Li-ion battery systems.
  • High Output Voltage: Supports output up to 12.6V.
  • High Current Capability: 7A continuous switch current for robust performance.
  • Integrated Power Switches: 19mohm (main) and 27mohm (rectifier) MOSFETs for high efficiency.
  • Adaptive Constant Off-Time Control: Provides excellent transient response and stable regulation.
  • Automatic PWM/PFM Operation: Optimizes efficiency across all load conditions.
  • Adjustable Switching Frequency: Configurable between 200kHz and 2.2MHz for design flexibility.
  • Soft Start Function: Built-in 4ms soft start limits inrush current during power-up.
  • Adjustable Peak Current Limit: Allows fine-tuning of system protection thresholds.
  • Comprehensive Protection: 13.2V OVP, cycle-by-cycle OCP, and thermal shutdown.
  • Compact VFQFN-11 Package: Ensures space efficiency with excellent thermal dissipation.
