How to Improve Buck Converter Light Load Efficiency with an LDO
https://www.electronics-lab.com/improve-buck-converter-light-load-efficiency-ldo/
By Michael Hartshorne @ digikey.com: Designing a DC/DC converter that only consumes micro amps of current at no load can be compared to fueling a muscle car with lighter fluid – you may get it to work, but it won’t be easy. High efficiency at full load currents is commonplace in most modern DC/DC converters; […]
