DESCRIPTION

The TPS53127 is a dual, adaptive on-time D-CAP2™ mode synchronous buck controller. The part enables

system designers to cost effectively complete the suite of various end equipment's power bus regulators with a

low external component count and low standby consumption. The main control loop for the TPS53127 uses the

D-CAP2™ Mode topology which provides a very fast transient response with no external component.

The TPS53127 also has a proprietary circuit that enables the device to adapt not only low equivalent series

resistance (ESR) output capacitors such as POSCAP/SP-CAP, but also ceramic capacitor. The part provides a

convenient and efficient operation with conversion voltages from 4.5 V to 24 V and output voltage from 0.76 V to

5.5 V.

The TPS53127 is available in the 24 pin RGE/PW package, and is specified from –40°C to 85°C ambient

temperature range.

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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
