The TPSM8291x devices are a family of high-efficiency, 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.
