The TPS43340QPHPRQ1 from Texas Instruments is a versatile quad-rail power supply designed for automotive applications. This integrated circuit combines two synchronous buck controllers with 0.6-A gate drive, a single synchronous 2-A buck converter, and a 300-mA linear regulator (LDO) with low quiescent current.
It supports an input voltage range of 4V to 40V, withstanding transients up to 60V, making it suitable for demanding automotive environments. The device operates with a programmable switching frequency between 150 kHz and 600 kHz. Key features include automatic low-power mode operation with low quiescent current (30 µA to 35 µA) and a low shutdown current of 5 µA typical.
The TPS43340QPHPRQ1 is housed in a 48-pin HTQFP package, designed for surface mounting. Its operating temperature range is -40°C to 125°C. The IC is qualified for automotive applications and meets AEC-Q100 test guidance.
This power supply is designed to power entire systems, including microcontrollers and other components, offering a comprehensive solution for power management in automotive electronics.
