Constant-on-time buck-boost regulator converts a positive input to a negative output

This is a LM5010 buck-boost regulator able to convert a positive input ranging from 10-50Vdc to -12V output. by Robert Bell @ www.edn.com Buck regulators find wide application as step-down regulators for converting large positive input voltages into a smaller positive output voltages....

Low profile regulator has digital power system management

Available as either a dual 10A or single 20A thin uModule regulator, the LTM4686 has a PMBus interface and is housed in a 16 x 11.9 x 1.82mm LGA package. The Power by Linear regulator’s low height allows the it to be placed on a PC board very close to its load such as an FPGA or...

5V Regulator Cap for 9V battery

David Cook built a 5V regulator to sit atop a 9V battery: For quick portable projects and temporary hacks, it is often faster to reuse a simple 5V regulator circuit than to integrate a power supply into the device design. My toolbox has an LED tester and magnifier light, so why not...
