The Texas Instruments TPS43330A-Q1 is a versatile power management integrated circuit designed for automotive applications. It combines a single boost controller with two synchronous buck controllers, offering a flexible solution for power conversion needs.
This device supports an input voltage range from 2V to 40V, with transient capabilities up to 60V. It features low quiescent current, typically 30µA with one buck on and 35µA with two bucks on, and a low shutdown current of less than 4µA. The buck output voltage can be regulated between 0.9V and 11V, while the boost output is selectable among 7V, 8.85V, or 10V.
The TPS43330A-Q1 operates with a switching frequency programmable between 150kHz and 600kHz, with an external synchronization option. It includes features such as separate enable inputs for each controller, selectable forced continuous mode or automatic low-power mode, and options for sense resistor or inductor DCR sensing for the buck controllers. The buck channels switch out-of-phase to reduce input ripple.
Packaged in an HTSSOP (DAP) with a 101.25 mm² area (12.5 mm x 8.1 mm), this component is qualified for automotive applications and AEC-Q100 certified. It is suitable for surface mount applications.
