图1TPS6215x内部结构图

TheTPS6215X family is an easy to use synchronous step down DC-DC converter optimized for applications with high power density. A high switching frequency of typically 2.5MHz allows the use of small inductors and provides fast transient response as well as high output voltage accuracy by utilization of the DCS-Control™ topology.
