TS33003 Overview
The TS33001/2/3 (1/2/3A) are DC/DC synchronous switching regulators with fully integrated power switches, internal pensation, and full fault protection. The switching frequency of 5MHz enables the use of extremely small filter ponents, resulting in smaller board space and reduced BOM costs. When the input current is greater than approximately 50mA, the TS33001/2/3 utilizes PWM voltage mode feedback with input...
