Description

TS33001 / 1A_3.3VoutThe TS33001/2/3 (1/2/3A) are DC/DC synchronous switchingregulators with fully integrated power switches, internalcompensation, and full fault protection. The switchingfrequency of 5MHz enables the use of extremely small filtercomponents, resulting in smaller board space and reducedBOM costs
