12V Regulated Inverter Supply

Friday, June 18th, 2010

When running 12V electronic devices from lead-acid battery banks, the voltage to the appliance can vary from below 11V with discharged batteries, to well above 14V during charging. Many appliances will not tolerate such a wide fluctuation and may perform poorly or be damaged. This step-up inverter, combined with a 12V fixed regulator, is a [...]

5V-12V Multiple Supply Switching regulator by L4970 and L4974A

Saturday, September 27th, 2008

Today take Multiple Supply Switching regulator Circuit. Come to deposit friends keep see in rows think out it can give Voltage supply about 5V 10A and 12V 3.5A. In same circuit by the character of Switching Regulator at use integrated readymade circuit. Work the character Synchronization between IC L4970 and L4974A. When friends see circuit [...]
