Evaluation kits (EV kits) are often the best tool for evaluating the applicability of a particular DC-DC converter for a specific application. Simulation, though never as accurate as the real hardware, is much faster and can be very effective for initial evaluations. Maxim Integrated’s MAX17504EVKITA is a 3.3V output EV kit for the MAX17504 member of the Himalaya family of high-voltage, synchronous step-down converters. The MAXIM_EESIM_MAX17504EVKITA.wxsch is a circuit file that enables simulation of this EV kit using the free EE-Sim SE simulation tool, downloadable from the Maxim Integrated website. EE-Sim SE is a variation of the commercial SIMPLIS/SIMetrix tool, which can also be used with this file.
MAXREFDES89# is an mbed®-compatible shield for the rapid development of brushed DC motor applications. The shield contains four MAX14871 full-bridge DC motor drivers for driving up to 4 motors. A MAX17501 DC-DC converter allows the system to operate from a single 7 to 36VDC power supply. Four MAX4704 4:1 multiplexers permit setting the current regulation mode of the MAX14871, while two MAX5387 digital potentiometers provide the ability to set the motor current limit. A MAX7300 GPIO expander supports interfacing each motor driver circuit to the mbed enabled microcontroller platform.

Due to its simplicity and low cost, the flyback converter is the preferred choice for low-to-medium isolated DC-DC power-conversion applications. However, the use of an optocoupler or an auxiliary winding on the flyback transformer for voltage feedback across the isolation barrier increases the number of components and design complexity.
