TPS53114 描述
The TPS53114 is a single, adaptive on-time D-CAP2™ mode synchronous buck controller. The TPS53114 enables system designers to complete the suite of various end equipment’s power bus regulators with cost effective low external component count and low standby current solution. The main control loop for the TPS53114 uses the D-CAP2™ mode control which provides a very fast transient response with no external components. The TPS53114 also has a circuit that enables the device to adapt to both low equivalent series resistance (ESR) output capacitors such as POSCAP or SP-CAP and ultra-low ESR ceramic capacitors. The device provides convenient and efficient operation with input voltages from 4.5 V to 24 V and output voltage from 0.
