Description

TS3300X EVB 0.5A 0.8VThe TS33010 is a DC/DC synchronous switching regulator with fully integrated power switches, internal compensation, and full fault protection. The switching frequency of 2.25MHz enables the use of extremely small filter components, resulting in smaller board space and reduced BOM costs

Features
