3.3V to 30V DC/DC converter using SN6505A
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, […]
Basic Switching Voltage Regulator Tutorial
https://www.electronics-lab.com/basic-switching-voltage-regulator-tutorial/
James Lewis @ baldengineer.com discuss about switching regulator types and uses. A switching voltage regulator is one of my favorite circuits. In school, they were the first circuits I built where I understood how transistors worked. In fact, they were the first circuit I saw an inductor being useful! Switching regulators are incredibly efficient when designed […]

Step up DC-DC converter is based on LM2577-ADJ IC, this project provides 12V output using 5V input, maximum output load 800mA. The LM2577 are monolithic integrated circuits that provide all of the power and control functions for step-up (boost), fly back, and forward converter switching regulators. The device is available in three different output voltage […]
Choose the right step-up/down voltage regulator for portable applications
https://www.electronics-lab.com/choose-the-right-step-updown-voltage-regulator-for-portable-applications/
Reno Rossetti & Inyong Kim discuss about the power needs on portable devices and help us choose the right regulator. A popular power source for portable devices is a single lithium-ion cell with 4.2V at full charge and 2.8V at end of discharge. However, some functions within portable electronics, such as a SIM card and […]
LTC7813 – Low IQ, 60V Synchronous Boost+Buck Controller
