NAME
FUNCTION
Current Limit/PWM Comparator Input. COMP is level-shifted and connected to the
1
1
COMP
inverting input of the PWM comparator. Pull up COMP to REF through a resistor and
connect an optocoupler from COMP to GND for proper operation.
2
SYNC
Bidirectional Synchronization Input. When synchronizing with other
MAX5095A/MAX5095Bs, the higher frequency part synchronizes all other devices.
Advance Clock Output. ADV_CLK is an 85ns clock output pulse preceding the rising

ADV_CLK
edge of OUT (see Figure 4). Use the pulse to drive the secondary-side synchronous
rectifiers through a pulse transformer or an optocoupler (see Figure 8).

REF
PWM Comparator/Overcurrent Protection Comparator Input. The current-sense signal is
compared to the level shifted voltage at COMP.
Timing Resistor/Capacitor Connection. A resistor R T from R T /C T to REF and capacitor C T
from R T /C T to GND set the oscillator frequency.
Power-Supply Ground. Place the V CC and REF bypass capacitors close to the IC to
minimize ground loops.
MOSFET Driver Output. OUT connects to the gate of the external n-channel MOSFET.
Power-Supply Input. Bypass V CC to GND with a 0.1μF ceramic capacitor or a parallel
combination of a 0.1μF and a higher value ceramic capacitor.
5V Reference Output. Bypass REF to GND with a 0.1μF ceramic capacitor or a parallel
combination of a 0.1μF and a higher value ceramic capacitor no larger than 4.7μF.
