Description

  • PMP9767.1, Efficient, LDO-free Power Supply for a 12-bit 500-MSPS ADC Reference Design. The electrical performance of data converters depends on the cleanliness of their supply voltages. Linear regulators (LDOs) are commonly used but have low efficiency and high power loss, which is unsuitable for portable applications. Using a switch mode power supply (SMPS) instead, such as the TPS62231 and TPS62237, is a cost-effective and efficient power supply solution. Such a solution does not degrade the performance of the 12-bit ADS540x family of analog to digital converters (ADCs) and does not waste excessive power
