ww1.microchip.comSep 10, 2007 · To reduce the loss at high current and to achieve lower output voltage, the freewheeling diode is replaced by a MOSFET with a very low ON state resistance RDSON. This MOSFET is turned on and off synchronously with the buck MOSFET. Therefore, this topology is known as a synchronous buck converter. A gate drive signal, which is the complement of ...

www.ti.comThe LM2576 is a buck (step-down) switching regulator, used as a constant-current source set to 2.6A. It provides good power conversion efficiency (about 80%) and oper-ates from a wide input voltage range. A constant-current feedback loop is established by holding the voltage at the Feedback pin of the LM2576 at 1.23V.
