Answer is no (cannot operate in CCM). The MAX17690 is a peak current mode, fixed-frequency switching controller specifically designed for the isolated Fly Back topology operating in Discontinuous Conduction…
The easiest way to get the model is to create a design with the online EE-Sim tool and then download the schematic from the download tab. The model will then be included with that schematic and you can…
Although the calculated value of the current sense resistor is 36mOhm, a 33mOhm resistor was chosen for the design to ensure the circuit didn't go into current limit too early.
The 33mOhm resistor is…
Although the calculated value of the current sense resistor is 62mOhm, a 60mOhm resistor was chosen for the design to ensure the circuit doesn't go into current limit before meeting the maximum output…
61mOhm is the calculated current sense resistor value, but a 60mOhm resistor was chosen for the design to ensure the circuit outputs a minimum of 600mA before going into current limit.
If exactly 61mOhms…
The datasheet of the transformers can be obtained by contacting the manufacturer directly by quoting the part number and Maxim's reference design number.
You should use the minimum given in the EC table of 90mV (for VSET = 0.8V). To design for worst case scenarios the minimum value for the maximum current limit threshold should be used on this pin to ensure…
The feedback is sampled during the Flyback period (low-side FET off) and is delayed enough to insure that ringing on the primary-side voltage during the initial portion of the Flyback period does not influence…
There is no restriction on Vout of DCM flyback using MAX17690. The EESIM simulaiton is limited to 48V however, for design assistance of projects having Vout greater than 48V please contact the technical…
