App note: How to use power inductors

Sunday, April 14th, 2019

A great guide from TDK about power inductors used in DC-DC converters. Link here As electronic devices become more advanced, the power supply voltage of LSIs used in them is lowered, so their power consumption can be reduced and their speed increased. However, a decrease in the power supply voltage...

3V3/30V DC/DC converter using SN6505A

Tuesday, May 3rd, 2016

Robert Gawron made a 3V3/30V DC/DC converter using SN6505A: 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 voltage as...

Output voltage control of DC/DC converters

Friday, February 5th, 2016

Thomas Fischl writes: Some applications needs to control the output voltage of a dc/dc converter instead using a fixed output voltage. For example battery chargers has to adjust the output voltage to the current battery level. This page shows how to add such a control function to a buck converter...

LM2596 DC-DC converter module testing

Monday, July 27th, 2015

Kerry D. Wong writes: In the video below, I tested this DC-DC converter board under various operating conditions and measured its efficiencies. To conclude, these switching regulator boards are well suited for low to medium current draw digital circuitry but for higher current applications a heat sink is needed and...

9V to 48V DC-DC converter

Friday, June 6th, 2014

Konstantin Dimitrov over at Electronics Lab writes: This project is a 8-12Vdc to +48Vdc DC-DC converter based on MC34063 switching regulator. It's a simple project of a DC-DC converter to make a phantom power supply for professional microphones. It can deliver 15-20mA at 48VDC. It 's based on MC34063 DC-DC...
