DESCRIPTION
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
0.76 V to 5.5 V.
The TPS53114 is available in the 16-pin TSSOP and HTSSOP packages, and is specified from –40°C to 85°C
ambient temperature range.
