The Texas Instruments TPS43333QDAPRQ1 is an automotive-qualified DC DC Switching Controller featuring a single boost and dual synchronous buck controller. It operates within an input voltage range of 4V to 40V, with transient capabilities up to 60V and operation down to 2V when the boost is enabled.
This controller supports step-up and step-down functions with a selectable boost output of 7V or 10V, and a buck output range from 0.9V to 11V. It boasts a maximum output current of 6A and a switching frequency range of 150kHz to 600kHz. Key control features include Enable, Frequency Control, Power Good, Soft Start, and Tracking.
The TPS43333QDAPRQ1 is housed in a 38-HTSSOP package and is designed for surface mount applications. Its operating temperature range is -40°C to 125°C (TJ). The device offers low quiescent current in power-save modes, with typical values of 30µA (one buck on) and 35µA (two bucks on), and a low shutdown current of less than 4µA.
Qualified for Automotive Applications, this controller meets AEC-Q100 standards, including Device Temperature Grade 1 (-40°C to 125°C Ambient Operating Temperature), HBM ESD Classification Level H2, and CDM ESD Classification Level C2. It is suitable for various automotive power management systems requiring efficient and reliable DC-DC conversion.
