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 TM 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 μ A (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
APPLICATIONS
better power conversion efficiency.
