Description

STEP DOWN CONV 4.5 TO 18V 14TSSOP
The TPS54325 device is an adaptive on-time DCAP2™ 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 DCAP2™ 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. 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 is available in the 14 pin HTSSOP package, and designed to operate from –40°C to 85°C.
