The TPS40195RGYR from Texas Instruments is a flexible synchronous buck controller. It operates from a nominal 4.5-V to 20-V supply, making it suitable for a variety of power management applications.
This controller implements voltage mode control and features a wide input operating voltage range of 4.5 V to 20 V. It supports an output voltage as low as 0.591 V with ±0.5% accuracy and can deliver up to 20 A of output current. The switching frequency can be set between 100 kHz and 600 kHz, allowing for design flexibility in terms of component size and efficiency.
Key features include 180° bi-directional out-of-phase synchronization, an internal 5-V regulator, and high and low MOSFET sense for overcurrent protection. The device also incorporates an enable function, power good signal, prebias startup, and selectable soft start. It is available in a 16-VQFN package with an exposed pad for enhanced thermal performance.
The operating temperature range is -40°C to 85°C, and it includes programmable UVLO and hysteresis, along with thermal shutdown at 150°C. The synchronous rectification feature contributes to higher efficiency.
