3-A buck-boost converter touts wide application

Milpitas, Calif. – Linear Technology promotes its LT3477 buck-boost DC/DC converter as one that’s suited to a wide variety of jobs, including service as a high-current LED driver. In the latter application, the wide-input (2.5-25 volt), 3-amp device, with dual rail-to-rail current sense amplifiers, combines a traditional voltage feedback loop and two current feedback loops to operate as a constant-current and a constant-voltage source.
