Push-Pull Driver Provides Isolated 5V at 1A


Abstract:In this design idea a simple circuit converts a regulated 5V input to an isolated 5V output at 1A. The efficiency of a
transformer H-bridge, push-pull driver, the MAX253, depends directly on the forward drops of the output rectifiers.

The circuit in Figure 1 converts a regulated 5V input to an isolated 5V output with 1A current-output capability. IC1 , a push-pull
transformer driver, powers a pair of cross-coupled power MOSFETs in a flip-flop-like configuration. In turn, the MOSFETs toggle
