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. Low-frequency 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.

The TPS62968 evaluation module (EVM) (SR142) facilitates the evaluation of the TPS62968, TPS62966, and TPS62964. The SR142 uses the 8A TPS62968 to output a 0.6V output voltage from input voltages between 3V and 17V. Due to extremely low noise, the TPS62968 is a high-efficiency alternative to (...)
