The LM5176QPWPRQ1 from Texas Instruments is a synchronous four-switch buck-boost controller designed for automotive applications, meeting AEC-Q100 standards. This device supports a wide input voltage range from 4.2V (or 2.5V with bias) up to 55V, with a maximum rating of 60V. The output voltage is flexible, ranging from 0.8V to 55V, and includes protection features like VOUT short protection.
This controller operates as a single-inductor buck-boost converter, enabling both step-up and step-down DC/DC conversion. It features an adjustable switching frequency between 100kHz and 600kHz, with options for frequency synchronization and dithering. Integrated 2A MOSFET gate drivers, cycle-by-cycle current limit, and optional hiccup mode enhance its control capabilities. Additional features include programmable input UVLO, soft-start, power good indication, and output overvoltage protection.
The LM5176QPWPRQ1 is supplied in a 28-pin HTSSOP package, suitable for surface mounting. Its operating temperature range is -40°C to 125°C (TJ), making it robust for demanding automotive environments. Documentation is available to aid in functional safety system design.
