TPS65251RHAR Product Details

The TPS65251RHAR is a synchronous step down three Buck Converter designed to simplify its application while giving the designer the option to optimize their usage according to the target application. The converters can operate in 5, 9, 12 or 15V systems and have integrated power transistors. The output voltage can be set externally using a resistor divider to any value between 0.8V and close to the input supply. Each converter features enable pin that allows a delayed start-up for sequencing purposes, soft-start pin that allows adjustable soft-start time by choosing the soft-start capacitor and a current limit (RLIMx) pin that enables designer to adjust current limit by selecting an external resistor and optimize the choice of inductor. The current mode control allows a simple RC compensation. 180° out of phase operation between Buck 1 and Buck 2, 3 (Buck 2 and 3 run in phase) minimizes the input filter requirements.
