3 Description
The TPS53014 is a single, adaptive on-time DCAP2
™ 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 V.
The TPS53014 is available in the 3-mm × 3-mm 10-
pin VSSOP (DGS) package and is specified for an
ambient temperature range of –40°C to +85°C.
