The Texas Instruments TPS61089RNRT is a high-performance, fully-integrated synchronous boost converter. It operates with an input voltage range of 2.7 V to 12 V and provides an adjustable output voltage from 4.5 V to 12.6 V. This device is capable of delivering up to 7 A of output current.
Key electrical specifications include a typical switch current limit of 11.4 A and a resistor-programmable peak current limit up to 10 A, suitable for high pulse current applications. The converter achieves up to 90% efficiency at a V_IN of 3.3 V, V_OUT of 9 V, and I_OUT of 2 A. It features an adjustable switching frequency ranging from 200 kHz to 2.2 MHz and a built-in soft start time of 4 ms.
For light load conditions, the TPS61089 supports PFM operation, while the TPS610891 variant offers forced PWM mode. Protection features include internal output overvoltage protection at 13.2 V, cycle-by-cycle overcurrent protection, and thermal shutdown, ensuring reliable operation.
The TPS61089RNRT is housed in a compact 2.00 mm x 2.50 mm VQFN HotRod package, suitable for surface mount applications. Its operating temperature range is -40°C to 125°C (TJ).
