  MSP430 Based LED Lantern Floating Buck Topology
  PDF, 165 Kb, File published: Aug 20, 2013
  It is always a challenge to drive a high-side mosfet switch using a simple microcontroller to design a buck topology switching regulator system. The main challenge is to generate the gate to source voltage for the mosfet switch that is more than the available input voltage. This limitation can be overcome by using a special topology of switching called "Floating BUCK" and avoid the use of any exte
