TPS43330Q1 Description

Short technical summary and product information.

The TPS43330-Q1 from Texas Instruments is a versatile DC DC switching controller designed for automotive and industrial multi-rail power distribution systems. This AEC-Q100 qualified device integrates two synchronous buck controllers and one pre-boost controller, enabling operation down to 2V input when the boost is enabled, and handling transients up to 60V.

 

Key electrical specifications include an input voltage range of 2V to 40V, with buck output voltage adjustable from 0.9V to 11V. The boost output can be selected from 7V, 10V, or 11V. The controller operates with a programmable switching frequency between 150 kHz and 600 kHz, or can be synchronized to an external clock. In low-power mode, quiescent current is as low as 30 µA (one buck on), and shutdown current is less than 4 µA.

 

The TPS43330-Q1 is housed in a 38-pin HTSSOP (DAP) package with dimensions of 12.50 mm x 6.20 mm. It is qualified for automotive applications, with a temperature grade of 1 (-40°C to 125°C ambient operating temperature). The device also features HBM ESD Classification Level 2 and CDM ESD Classification Level C4B.

 

This part is not recommended for new designs, but remains available for existing customers. An alternate part, TPS43330A-Q1, offers similar functionality.
