DESCRIPTION  
The TPS53014 is a single, adaptive on-time D-CAP2™ mode synchronous buck controller. The TPS53014  
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  
TPS53014 uses the D-CAP2™ mode control which provides a very fast transient response with no external  
compensation components. The Adaptive on-time control supports seamless transition between PWM mode at  
higher load condition and Eco-mode™ operation at light load. Eco-mode™ allows the TPS53014 to maintain high  
efficiency during lighter load conditions. The TPS53014 is also able 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 28 V and output voltage from  
0.77 V to 7.0 V.  
The TPS53014 is available in the 3.0mm x 3.0 mm 10-pin VSSOP (DGS) package, and is specified for an  
ambient temperature range of –40°C to 85°C.
