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.
