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