General Desc ription
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-fre-
quency power supplies. Isolated or nonisolated push-
pull 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 program-
mable 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 opera-
tion during brownout conditions.
A single external resistor programs the oscillator frequen-
cy 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 auto-
motive 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. Exercise caution.
