Several power supply topologies, including SEPIC and flyback converters [1], generate a non-isolated, positive DC voltage from a positive DC input voltage range that extends both above and below the ...
A buck-boost controller IC with four external switching MOSFETs can operate from input voltages above, below, or equal to the output voltage, enabling them to regulate the light output for a string of ...
Containing independent boost and buck controllers, the LTC7813 from Linear Technology operates from an input voltage of 4.5 V to 60 V. The synchronous DC/DC controller can regulate two separate ...
IR’s new IRS2505L power factor correction boost IC comes in a 5-pin SOT23 package for switch mode power supply, LED drivers, and fluorescent and HID electronic ballast applications. The IC features a ...
