The MAX5068 is a high-frequency, current-mode,pulse-width modulation (PWM) controller that integratesall the building blocks necessary for implementing AC-DC or DC-DC fixed-frequency power supplies. Isolatedor nonisolated power supplies are easily constructedusing either primary- or secondary-side regulation.Current-mode control with leading-edge blanking sim-plifies control-loop design, and a programmable inter-nal slope-compensation circuit stabilizes the currentloop when operating at duty cycles above 50%. TheMAX5068A/B limit the maximum duty cycle to 50% foruse in single-ended forward converters. TheMAX5068C/D/E/F allow duty cycles up to 75%. TheMAX5068 features an accurate externally programma-ble oscillator that simplifies system design.An input undervoltage lockout (UVLO) programs theinput-supply startup voltage and ensures proper opera-tion during brownout conditions.A single external resistor programs the output switchingfrequency from 12.5kHz to 1.25MHz. The MAX5068A/B/C/E provide a SYNC input for synchronization to anexternal clock. The maximum FET-driver duty cycle is50% for the MAX5068A/B and 75% for the MAX5068C/D/E/F. Programmable hiccup current limit providesadditional protection under severe faults.The MAX5068 is specified over the -40°C to +125°Cautomotive temperature range and is available in a16-pin thermally enhanced TSSOP-EP package. Refer tothe MAX5069 data sheet for dual FET-driver applications.Warning: The MAX5068 is designed to work with highvoltages. Exercise caution.
