The Texas Instruments TPS40050PWPR is a synchronous buck DC/DC switching controller designed for power management applications. It features a wide input voltage range from 8V to 40V and can provide an output voltage from 0.7V up to 35V, with a maximum output current capability of 20A.
This controller operates at a nominal frequency of 500kHz, with a programmable fixed-frequency option up to 1MHz. It supports a maximum duty cycle of 94% (or 100% as per manufacturer page) and includes control features such as current limit, enable, frequency control, and soft start. The device is housed in a 16-HTSSOP package suitable for surface mounting.
Key electrical characteristics include a typical quiescent current of 0.0015A and an internal 0.7V reference voltage. The TPS40050PWPR is noted as 'NOT RECOMMENDED FOR NEW DESIGNS' by the manufacturer, indicating that while it remains available for existing customers, new projects should consider alternative components like the LM25145 for potentially improved performance and smaller solution size.
Applications for this controller include power modules, networking, telecom, and industrial servers. Its design facilitates efficient power conversion in various demanding environments.
