The TPS53114 is a single, adaptive on-time D-CAP2TM 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 TPS53114 uses the D-CAP2TM mode topology which provides a very fast transient response with no external components. The TPS53114 also has a PROPRIETARY circuit that enables the device to adapt to not only low equivalent series resistance (ESR) output capacitors such as POSCAP/SP-CAP, but also ceramic using the CER pin. The part provides convenient and efficient operation with conversion voltages from 4.5V to 24V and output voltage from 0.76V to 5.5V.
