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 평가 모듈
TPSM82916 평가 모듈(EVM)(SR073)을 통해 TPSM82916 및 TPSM82914를 쉽게 평가할 수 있습니다. SR073은 6A TPSM82916을 사용하여 3V~17V 사이의 입력 전압에서 1.2V 출력 전압을 출력합니다. 극히 낮은 잡음으로 인해 TPSM82916은 잡음에 민감한 회로에서 LDO(저손실) 선형 레귤레이터를 대체하는 고효율 제품입니다.
