TPS54325PWPR原装 DC-DC 开关稳压器 的描述：
The TPS54325 device is an adaptive on-time D-CAP2? mode synchronous buck converter. The TPS54325 device enables system designers to complete the suite of various end equipment’s power bus regulators with a cost effective, low component count, low standby current solution.
The main control loop for the TPS54325 uses the D-CAP2? mode control which provides a very fast transient response with no external components. The TPS54325 also has a proprietary circuit that enables the device to adapt to both low equivalent series resistance (ESR) output capacitors, such as POSCAP or SP-CAP, and ultra-low ESR ceramic capacitors. The device operates from 4.5-V to 18-V VCC input , and from 2.0-V to 18-V VIN input power supply voltage.
