The Texas Instruments TPS55340QRTETQ1 is an AEC-Q100 qualified DC/DC switching regulator designed for automotive applications. It supports boost, SEPIC, and flyback topologies, offering flexibility for various power management designs.
This device features a wide input voltage range from 2.9 V to 38 V and an internal 5-A, 40-V low-side MOSFET switch. The output voltage is adjustable, and the regulator operates with a switch current limit of typically 6.6 A. It includes features such as frequency synchronization, light load efficiency, and nonsynchronous operation.
The TPS55340QRTETQ1 is housed in a 16-WQFN (3 mm x 3 mm) package with a PowerPad for enhanced thermal performance. The operating temperature range is -40°C to 125°C (TA), making it suitable for demanding environments. Protection features include cycle-by-cycle current limit, thermal shutdown, and undervoltage lockout (UVLO).
Key electrical characteristics include a reference voltage accuracy of ±0.7%, a low operating quiescent current of 0.5 mA, and a shutdown supply current of 2.7 µA. The switching frequency is adjustable from 100 kHz to 2.5 MHz, with synchronization capability to an external clock.
