TEXAS INSTRUMENTS TPS54325EVM. 评估板, TPS54325, 3A 同步降压转换器
The is an evaluation module for TPS54325 5V to 17V input 3A output current converter. The TPS54325 is a single, adaptive on time DCAP2 mode synchronous buck converter. System designers may use the TPS54325 to complete various end equipment dc/dc converters with a low cost, low component count, low standly current solution. The main control loop for the TPS54325 uses the DCAP2 mode that optimised for low ESR output capacitors such as POSCAP, SP CAP, High Polymer Chemistry or ceramic types. This control loop implementation provides fast transient response with no external compensation components. The TPS54325 dc/dc synchronous converter is designed to provide up to a 3A output from an input control voltage source of 4.5V to 18V, input power voltage source of 2.0V to 18V and output voltage from 0.76V to 5.5V.
