Introduction
Linear Technology’s LT3471 is a space saving and extremely versatile dual switching regulator available in a tiny 3mm × 3mm DFN package. With a 2.4V to 16V input range, the device can easily implement any combination of boost, inverting and SEPIC topologies to generate two positive and/or negative outputs up to ±40V. It can readily make the two output voltages track each other with minimal additional circuitry, or it can independently regulate the outputs, thus saving space by replacing two separate ...
