More Information

The TPS65261, TPS65261-1 is a monolithic triple synchronous step-down (buck) converter with 3A/2A/2A output currents. A wide 4.5V to 18V input supply voltage range encompasses the most intermediate bus voltages operating off 5V, 9V, 12V or 15V power bus. The converter, with constant frequency peak current mode, is designed to simplify its application while giving designers options to optimize the system according to targeted applications. The switching frequency of the converters can be adjusted from 250kHz to 2MHz with an external resistor. The 180° out-of-phase operation between Buck1 and Buck2, 3 (Buck2 and 3 run in phase) minimizes the input filter requirements.
