Description
General part information
TPS53125 Series
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-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.
