Flexible Solution for Push-Pull and Half-/Full-

Bridge Power Supplies, Ideal for High-Power

Applications

MAX5069

The MAX5069 is a high-frequency, current-mode PWM controller with dual

MOSFET drivers. The IC integrates everything necessary for implementing AC-

DC or DC-DC xed-frequency power supplies. Isolated or nonisolated, push-

pull and half-/full-bridge power supplies are easily constructed using either

primary- or secondary-side regulation. An input undervoltage lockout (UVLO)

programs the input-supply startup voltage and ensures proper operation

during brownout conditions. The MAX5069 operates at over 100W.
