3 Description
The TPS8269xSIP device is a complete 500 mA /
800 mA, 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 TPS8269xSIP 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 3-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 23 μA
(typical) 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 TPS8269xSIP is packaged
in a compact (2.9 mm × 2.3 mm) and low profile (1
mm) BGA package suitable for automated assembly
by standard surface mount equipment.
