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 equipments
power bus regulators with a low external component count and low standby consumption. The main
control loop for the TPS53125 uses the D-CAP™ 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 24-pin RGE and PW packages, and is specified from –40°C to
85°C ambient temperature range.
