19-2830; Rev 0; 4/03 EVAALVUAAILTAIOBNLEKIT Synchronizable, High-Frequency Current- and Voltage-Mode PWM Controllers for Isolated Supplies MAX8540/MAX8541 General Description The MAX8540/MAX8541 pulse-width-modulated (PWM) controllers for forward/flyback isolated DC-to-DC converters provide maximum flexibility to power-supply designers and reduce external component count. These controllers allow common PC board layout for currentmode (MAX8540) and voltage-mode (MAX8541) designs. Both controlle.

19-2830; Rev 0; 4/03 EVAALVUAAILTAIOBNLEKIT Synchronizable, High-Frequency Current- and Voltage-Mode PWM Controllers for Isolated Supplies MAX8540/MAX8541 General Description The MAX8540/MAX8541 pulse-width-modulated (PWM) controllers for forward/flyback isolated DC-to-DC converters provide maximum flexibility to power-supply designers and reduce external component count. These controllers allow common PC board layout for currentmode (MAX8540) and voltage-mode (MAX8541) designs. Both controllers feature adjustable switching frequency and external synchronization from 200kHz to 1MHz. Active-high and active-low enable, undervoltage protection (UVP), and overvoltage protection (OVP) reduce external component count. Maximum duty cycle is adjustable, and the feed-forward function scales the maximum duty cycle with input voltage to limit the maximum volt-seconds applied to the transformer primary. The MAX8540 allows the user to select the value of slope compensation to further optimize mag.
