The TPS54325-Q1 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-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. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 SWIFT, D-CAP2, PowerPAD are trademarks of Texas Instruments. 3 Blue-ray Disc is a trademark of Blu-ray Disc.
