The Texas Instruments TPS40074RHLT is a synchronous step-down DC-DC switching controller. It is designed to operate over a wide input voltage range of 4.5V to 28V, providing design flexibility for various applications.
Key electrical specifications include a switching frequency programmable up to 1MHz and a maximum duty cycle of 95%. The controller supports a single positive output and features synchronous rectification for improved efficiency. It also includes control features such as current limit, enable, frequency control, power good, and soft start.
The TPS40074RHLT is housed in a 20-VQFN exposed pad package, suitable for surface mounting. Its operating temperature range is -40°C to 85°C (TA). This component is ideal for applications requiring efficient voltage regulation in a compact form factor.
This controller utilizes voltage feed-forward control techniques for good line regulation and fast response to input line transients. It incorporates internal gate drivers for external N-channel MOSFETs.
