LTM8003 – 40VIN, 3.5A Step-Down μModule Regulator
https://www.electronics-lab.com/ltm8003-40vin-3-5a-step-down-%ce%bcmodule-regulator/
LTM8003 is a step-down DC/DC µModule (micro-module) regulator with a 40V input voltage rating (42V abs. Max.) and 3.5A of continuous (6A peak) output current. The LTM8003’s pinout is FMEA (failure mode effects analysis) compliant, so the output voltage stays at or below the regulation voltage in the event of short-circuit to GND, short-circuit to […]

LED current regulator has low dropout
https://www.electronics-lab.com/led-current-regulator-low-dropout/
Peter Demchenko @ edn.com This Design Idea circuit regulates the current through one or more LEDs, making it almost independent of supply voltage. Its main advantage is a very small dropout voltage, which can be less than 100mV. The design could find use on LED strips, where the voltage can vary along the length due […]
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; […]
