Description:

High-frequency current- and voltage-mode pwm controllers.

MAX8540, High-Frequency Current- and Voltage-Mode PWM Controllers

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)

MAX8540 Features

* useradjustable ramp magnitude for the PWM comparator. A cycle-by-cycle current-limit function controls the peak primary current during overload and short circuit. Both controllers can be set to latch off or to hiccup when a short circuit is detected. The number of current-limited cycles to initiate
