图1TPS82085内部结构图

The TPS82085 device is a 3-A step-down converter MicroSiP™ module optimized for small solution size and high efficiency. The power module integrates a synchronous step-down converter and an inductor to simplify design, reduce external components and save PCB area. The low profile and compact solution is suitable for automated assembly by standard surface mount equipment.
