com Parallelable Secondary-Side Synchronous Rectifier Driver and Feedback-Generator Controller ICs General Description The MAX5058/MAX5059 enable secondary-side synchronous rectification in isolated power supplies using widely available power MOSFETs.
These devices facilitate the commutation of the secondary-side MOSFETs by providing a clean gate-drive signal that is synchronized to the power MOSFET switching in the primary side of the isolation transformer.
The MAX5058/MAX5059 complement the MAX5051 and MAX5042/MAX5043 primaryside PWM ICs and enable the design of high-efficiency synchronously rectified isolated power supplies.
Simultaneous conduction of the primary side and the freewheeling synchronous rectifier MOSFET is avoided by having a look-ahead signal (before the primary-side MOSFETs turn ON), thus eliminating large current spikes resulting from a shorted transformer secondary.
An on-board error amplifier with a versatile current referen...
