3 Description
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 enpasses 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...
