4.5 V至18 V, 3 A输出同步降压具有集成FET SWITCHER ( SWIFTâ ?? ¢ ) 4.5-V to 18-V, 3-A OUTPUT SYNCHRONOUS STEP DOWN SWITCHER WITH INTEGRATED FET SWIFTâ¢
The TPS54325-Q1 is an adaptive on-time D-CAP2™ mode synchronous buck converter. The TPS54325-Q1 enables system designers to complete the suite of various end equipments power bus regulators with a cost effective, low component count, low standby current solution. The main control loop for the TPS54325-Q1 uses the D-CAP2 mode control which provides a very fast transient response with no external components. The TPS54325-Q1 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. The output voltage can be programmed between 0.76 V and 5.5 V. The device also features an adjustable slow start time and a power good function. The TPS54325-Q1 is available in the 14 pin HTSSOP package, and designed to operate from 40°C to 105°C.
