DESCRIPTION
The TPS53125 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 TPS53125 uses the
D-CAP2 Mode topology which provides a very fast transient response with no external component.
The TPS53125 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 TPS53125 is available in the 24 pin RGE/PW package, and is specified from –40°C to 85°C ambient
temperature range.
