MAX17606, a secondary-side synchronous MOSFET driver, helps in replacing the secondary diode with a MOSFET. This improves the efficiency and simplifies thermal management. This application note provides the step-by-step procedure for designing the different components of the MAX17690 + MAX17606-based synchronous flyback design. Design Example Apr 05, 2012 · Now, this driver is really good when it comes to efficiency and output current in comparison with other topologies, however, it is quite difficult to obtain more than 40 kilovolts out of a single DST flyback without increasing input voltage, thus stressing the components more, or without an external high voltage multiplier.
The easiest way to drive a MOSFET using the boostrap based drive is to use a dedicated high side MOSFET driver. Some drivers come with just the high-side driver while many come with both high-side and low-side drivers. IR2117, for example, is one driver that contains a single driver that can be used to drive a high-side MOSFET driver.
