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.A single external resistor programs the oscillator frequency from 50kHz to 2.5MHz. The MAX5069A/D provide a SYNC input for synchronization to an external clock. The maximum FET-driver duty cycle for the MAX5069 is 50%. Programmable dead time allows additional flexibility in optimizing magnetic design and overcoming parasitic effects. Programmable hiccup current limit provides additional protection under severe faults.The MAX5069 is specified over the -40°C to +125°C automotive temperature range and is available in a 16-pin thermally enhanced TSSOP-EP package. Refer to the MAX5068 data sheet for single FET-driver applications.Warning:The MAX5069 is designed to work with high voltages.
