The MAX5069 is a high-frequency, current-mode,
pulse-width modulation (PWM) controller (with dual
MOSFET drivers) that integrates all the building blocks
necessary for implementing AC-DC or DC-DC fixed-frequency
power supplies. Isolated or nonisolated pushpull
and half/full-bridge power supplies are easily
constructed using either primary- or secondary-side
regulation. Current-mode control with leading-edge
blanking simplifies control-loop design and a programmable
internal slope-compensation circuit stabilizes the
current loop when operating at duty cycles above 50%.
An input undervoltage lockout (UVLO) programs the
input-supply startup voltage and ensures proper operation
during brownout conditions.
