3 Description
The TPS6296x devices are a family of high-efficiency,
low noise, and low ripple current mode synchronous
buck converters. 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 1.1MHz, 700kHz, or 500kHz, 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.
