TPS65262 Triple Synchronous Buck Converters

Texas Instruments TPS65262 Triple Synchronous Buck Converters are monolithic triple synchronous step-down (buck) converters with 3A/1A/1A output current. A wide 4.5V to 18V input supply voltage range encompasses the most intermediate bus voltage operating off 5V, 9V, 12V, or 15V power bus. The converters, with constant frequency peak current mode, are designed to simplify its application while giving designers options to optimize the system according to targeted applications. The device operates at a 600kHz fixed switching frequency. The loop compensations for buck2 and buck3 have been integrated for fewer external components. The 180° out-of-phase operation between buck1 and buck2, 3 (buck2 and buck3 run-in phase) minimizes the input filter requirements.
