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, under
voltage protection (UVP), and over
voltage protection (OVP) reduce ex...
