Semtech Corporation TS30011
The TS30011 (1A), TS30012 (2A) and TS30013 (3A) are DC/DC synchronous switching regulator with fully integrated power switches, internal compensation, and full fault protection. The switching frequency of 1MHz enables the use of small filter components resulting in minimal board space and reduced BOM costs. The TS30011/12/13 utilizes current mode feedback in normal regulation PWM mode.| Part No. | TS30011 |
