"WebWhen looking for an LDO to filter noise, the key specification to look for is the power supply ripple rejection ratio (PSRR). PSRR is the measurement of the output ripple compared to the input ripple. The higher the PSRR, the better the LDO is for rejecting input ripple. Figure 9 is an illustration of the buck converter and LDO connection. Note ... " - Buck boost ldo

WebMar 11, 2024 · Ⅴ. LDO vs DC/DC. To begin with, in terms of efficiency, DC/DC is generally significantly more efficient than LDO, which is defined by its operating principle. Second, there are Boost, Buck, and Boost/Buck in DC/DC, Some people lump ChargePump into this category as well, despite the fact that LDO only has a step-down kind. WebMar 21, 2024 · I think you can just set the boost converter to output 12V and omit the buck converter altogether, because power input is from USB and there's no need to drop voltage down (under normal circumstances). Or, if noise is a concern, you might use an LDO in place of the buck converter. However in case of this device the 12V rail is fairly noisy.
