The TPS65251-3RHAT from Texas Instruments is a high-performance synchronous triple buck converter designed for efficient power management. It features a wide input supply voltage range from 4.5V to 18V, making it suitable for various applications.
This converter offers three independent buck outputs, with the first capable of continuous loading up to 3A and the other two up to 2A each. The output voltage is adjustable from 0.8V up to V_IN - 1V. Key electrical features include current-mode control, adjustable switching frequency from 300kHz to 2.2MHz, and integrated FETs.
The device supports features like adjustable current limit, soft-start, enable pins for each buck, and frequency synchronization. It also includes power good indication and automatic PFM/PWM operation for light-load efficiency. The TPS65251-3RHAT is housed in a 40-pin VQFN package measuring 6mm x 6mm, suitable for surface mount applications.
