The Texas Instruments TPS40051 is a DC-DC switching controller designed for power management applications. It features a wide input voltage range from 8V to 40V and supports output voltages from 0.7V to 35V, with a maximum output current of 20A.
Key electrical specifications include a programmable fixed frequency up to 1 MHz, a maximum duty cycle of 85%, and a typical quiescent current of 1.5 mA. The controller utilizes a voltage mode control architecture and includes internal gate drive outputs for high-side and synchronous N-channel MOSFETs. It also offers features such as enable, frequency synchronization, thermal shutdown, and programmable high-side current limit.
This controller is housed in a 16-pin HTSSOP PowerPAD package, measuring 32 mm² (5 mm × 6.4 mm), and is designed for surface mount applications. The operating temperature range is -40°C to 85°C.
Note: This product is not recommended for new designs. Consider alternate products like the LM25145 for new projects.
