图1TPS84250内部结构图

TheTPS84250 is an easy-to-use integrated power solution that combines a 2.5-A DC/DC converter with an inductor and passives into a low profile, QFN package. This total power solution allows as few as five external components and eliminates the loop compensation and magnetics part selection process.

TheTPS84250 can operate over a wide input voltage range of 7V to 50V and produce output voltages from 2.5V to 15V. The performance of the device varies over this wide operating range, and there are some important considerations when operated near the boundary limits. This section offers guidance in selecting the optimum components depending on the application and operating conditions.
