The TPSM8291x devices are a family of high-efficiency, low noise, and low ripple current mode synchronous buck modules. 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 2.2MHz, 1.4MHz, or 1MHz, 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.

TPSM82916EVM — TPSM82916 評估模組
TPSM82916 評估模組 (EVM) (SR073) 可協助評估 TPSM82916 和 TPSM82914。SR073 使用 6A TPSM82916，從介於 3V 到 17V 之間的輸入電壓輸出 1.2V 輸出電壓。由於雜訊極低，因此在雜訊敏感電路中，TPSM82916 是低壓差 (LDO) 線性穩壓器的高效率替代方案。
