FUNCTION
Zero-Inductor Current-Sense Comparator Input. The source voltage of the freewheeling FET (N4 in the Typical
Application Circuit ) is sensed. The gate drive is terminated when this voltage becomes positive during a primary
power-OFF cycle.
Zero-Inductor Current-Sense Comparator Negative Input
Ground Connection
Negative Input of the Share-Force Amplifier. Connect the SFN inputs together from all the power-supply
secondaries, then connect to the load return terminal (isolated GND). Connect to GND when current sharing is not
used.
Positive Input of the Share-Force Amplifier. Connect the SFP pins together from all the power-supply secondaries.
Leave this pin unconnected when current sharing is not used.

Thermal Warning Flag Output
Margin-Up Logic Input. When toggled high, the power-supply output voltage is set to the high margin.
Margin-Down Logic Input. When toggled high, the power-supply output voltage is set to the low margin.
Resistor Connection for Margin-Down
Resistor Connection for Margin-Up
Reference Current Output. A resistor from this current source output to GND sets the reference voltage used by
the error amplifier.
Compensation Connection for the Error Amplifier. The feedback optocoupler LED is also connected to this point.
This open-drain output is capable of sinking at least 5mA.
Inverting Input of the Error Amplifier. A voltage-divider connected to this input scales the power-supply output
voltage for regulation.
Output of the Remote-Sense Amplifier
Negative Input of the Remote-Sense Amplifier. Connect this to the negative terminal of the load.
Positive Input of the Remote-Sense Amplifier. Connect this to the positive terminal of the load.
Output of the Current-Sense Amplifier. It can be used to monitor the output current.
Connect this input to the negative terminal of the output current-sense resistor. Connect to GND when not used.
Connect this input to the positive terminal of the output current-sense resistor. Connect to GND when not used.
Compensation Pin for Internal +4V Preregulator. A minimum 1μF low-ESR capacitor must be connected to this pin
for bypassing.
Supply Connection for the IC and Input to the Internal 5V (MAX5058) or 10V (MAX5059) Regulator. Maximum
voltage on this input is 28V.
Regulated +5V (MAX5058) or +10V(MAX5059) Output Used by the Internal Circuitry and the Output Drivers. A
minimum 1μF capacitor must be connected to this pin for bypassing.
Input for the Synchronizing Pulse. This pulse is provided by the primary-side power IC.
Supply Connection for the Output Drivers. Can be connected to V REG for 5V (MAX5058) or 10V (MAX5059)
operation.
Driver Output for the Rectifying MOSFET
Power-Ground Connection. Return ground connection for the gate-driver pulse currents.

Exposed Pad. This is the exposed pad on the underside of the IC. Connect the exposed paddle to GND and to a
large copper ground plane to aid in heat dissipation.
