Abstract: , isolated power supply, current-mode, PWM, synchronous rectifier, switch mode, fixed frequency, step down , scheme is used to guarantee gate drive voltage on the freewheeling MOSFET when the transformer winding , changing from 40V to 60V. The forward path synchronous MOSFET Q1 is turned on when the transformer voltage , freewheeling MOSFET Q4 is turned on when switch Q3 is turned off and the transformer voltage reverses. Once the transformer voltage goes to zero, MOSFET Q2 is kept on because there is no discharge path on the Maxim Integrated Products

Abstract: discharges, the regulator must first step down, and then step up. This requirement precludes use of the simpler, one-function regulator topologies that can only step down, step up, or invert. One effective , capacitively coupled to the switching circuitry (Figure 1). The absence of a transformer is one of several , VOUT approaches VIN. Its power-conversion efficiency peaks at 86%, near 200mA (Figure 1). Figure 2. Typical dc-dc boost converters provide a current path from input to output, even when powered down.
