3 Description
The TPS8267x device is a complete 600mA, DC/DC
step-down power supply intended for low-power
applications.
Included
in
the
package
are
the
switching
regulator,
inductor
and
input/output
capacitors. No additional components are required to
finish the design.
The
TPS8267x
is
based
on
a
high-frequency
synchronous step-down dc-dc converter optimized for
battery-powered
portable
applications.
The
MicroSiP™ DC/DC converter operates at a regulated
5.5-MHz switching frequency and enters the power-
save mode operation at light load currents to maintain
high efficiency over the entire load current range.
The PFM mode extends the battery life by reducing
the quiescent current to 17
μA (typ) during light load
operation. For noise-sensitive applications, the device
has PWM spread spectrum capability providing a
lower noise regulated output, as well as low noise at
the input. These features, combined with high PSRR
and AC load regulation performance, make this
device suitable to replace a linear regulator to obtain
better power conversion efficiency.
The TPS8267x is packaged in a compact (2.3mm x
2.9mm) and low profile (1.0mm) BGA package
suitable for automated assembly by standard surface
mount equipment.
