3 Description
The TPSM8291x devices are a family of highefficiency,
low noise, and low ripple current mode
synchronous buck modules. The devices are
designed for noise sensitive applications that normally
use an LDO for post regulation such as high-speed
ADCs, clock and jitter cleaner, serializer, de-serializer,
and radar applications.
To reduce the output voltage ripple, the device
loop compensation is designed to operate with an
optional second-stage ferrite bead L-C filter. Lowfrequency
noise levels, similar to a low-noise LDO,
are further achieved by filtering the internal voltage
reference with a capacitor connected to the NR/SS
pin. Combined, these features allow for an output
voltage ripple below 10μVRMS.
The device operates at a fixed switching frequency of
2.2MHz, 1.4MHz, or 1MHz, and can be synchronized
to an external clock. An optional spread spectrum
modulation scheme spreads the DC/DC switching
frequency over a wider span, which lowers the mixing
spurs.
