The Texas Instruments TPS65251 is a high-performance synchronous triple buck converter. It is designed to operate within a wide input supply voltage range of 4.5 V to 18 V, making it suitable for various power applications.
This converter offers three buck output channels, with Buck 1 capable of continuous loading up to 3 A, and Buck 2 and 3 supporting up to 2 A each. The device features an adjustable switching frequency that can be set externally from 300 kHz to 2.2 MHz, allowing for design flexibility and optimization. It also includes features such as adjustable current limit, dedicated enable pins for each buck, frequency synchronization, phase interleaving, power good indication, and adjustable soft-start.
The TPS65251 utilizes current-mode control with a simple compensation circuit. It is housed in a 40-pin VQFN package measuring 6 mm x 6 mm. The operating temperature range is from -40°C to 125°C.
Key electrical characteristics include a 1% accuracy reference voltage and an optional low-power mode for light loads. The device supports synchronous rectification for improved efficiency.
