1 TPSM8291xEVM Evaluation Module

The TPSM8291xEVM (BSR213) facilitates the evaluation of the TPSM8291x 2-A and 3-A pin-to-pin compatible low-noise (< 20 μVRMS) and low-ripple (< 10 μVRMS) buck power modules in small 4.5-mm by 5.5-mm QFN packages. The BSR213-001 uses the 3-A TPSM82913 to output a 1.2-V output voltage from input voltages between 3 V and 17 V. The BSR213-002 uses the 2-A TPSM82912 to output a 3.3-V output voltage from input voltages up to 17 V. Due to its extremely low noise, the TPSM8291x is a high-efficiency alternative to low-dropout (LDO) linear regulators in noise-sensitive circuits, such as data converters, clocks, and amplifiers in telecom infrastructure, medical, test and measurement, and aerospace and defense applications.
