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.
