4.5-V to 18-V, 3-A OUTPUT SYNCHRONOUS STEP DOWN

SWITCHER WITH INTEGRATED FET (SWIFT™)

FEATURES

DESCRIPTION

•

D-CAP2™ Mode Enables Fast Transient

Response

The TPS54325 is an adaptive on-time D-CAP2™

mode synchronous buck converter. The TPS54325

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. 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.
