TPS53015DGSR

The TPS53015 device is a single, adaptive on-time
D-CAP2 ™ mode synchronous buck controller. The
device enables system designers to complete the
suite of various end equipment power bus regulators
with cost effective low external component count and
low standby current solution. The main control loop
for the TPS53015 uses the D-CAP2 mode control
which provides a very fast transient response with no
external compensation components. The adaptive ontime control supports seamless transition between
PWM mode at higher load condition and Eco-mode™
operation at light load. Eco-mode operation allows the
device to maintain high efficiency during lighter load
conditions. The device is also able to adapt to both
low equivalent series resistance (ESR) output
capacitors such as POSCAP or SP-CAP and ultralow 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 TPS53015 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.
