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 […]
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; […]
150V synchronous step-down DC/DC includes surge protection
https://www.electronics-lab.com/150v-synchronous-step-dcdc-includes-surge-protection/
Linear Technology designed the LTC3895 to be a non-isolated DC/DC controller with a high input voltage capability that can eliminate the need for surge suppression and operate continuously with a high input voltage. The synchronous step-down switching regulator controller drives an all N-channel MOSFET power stage. Its 4V to 140V (150V abs. Max.) input voltage […]

https://www.electronics-lab.com/3v330v-dcdc-converter-using-sn6505a/
Bob tipped us with his latest project. It’s a 3V3/30V DC/DC converter using SN6505A from TI. Recently I’v got my samples of SN6505A, it’s a really nice IC, so I decided to make a simple DC/DC converter to get familiar with it. What I like in this chip is that it can operate on input […]
0.8A step-up DC/DC converters in a tiny package
https://www.electronics-lab.com/0-8a-step-dcdc-converters-tiny-package/
Torex Semiconductor’s XC9141/XC9142 series of 0.8A step-up DC/DC converters come with an input–output disconnection function (load disconnection function) to prevent malfunctioning during standby, and for device functionality that enables power supply to RTC. When the output voltage is 3.3V, the IC can start from an input voltage of 0.9V with a resistance load of 100Ω, […]
