IR3506
A synchronous rectification disable comparator is used to detect converter CSIN- pin voltage, which represents
local converter output voltage. If the voltage is below 75% of VOUT1 and negative current is detected during
startup, GATEL drives low, which disables synchronous rectification and eliminates negative current during power-
up. Once VOUT1 reaches approximately 75 % of its nominal value, synchronous rectification is regain and can not
be disable again until the startup.
The gate drivers pull low if the supply voltages are below the normal operating range. An 80k
resistor is connected
across the GATEH/GATEL and PGND pins to prevent the GATEH/GATEL voltage from rising due to leakage or
other causes under these conditions.
Over Voltage Protection (OVP)
Output over-voltage might occur due to a high side MOSFET short or if the output voltage sense path is
compromised. If the over-voltage protection comparators sense that either VOUT1 pin voltage exceeds VREF1 by
260mV or VOUT2 exceeds VREF1, the over voltage fault latch is set which pulls the error amplifier output low to
turn off the converter power stage. The IR3522 communicates an OVP condition to the system by raising the
CROWBAR pin voltage to within V(VCCL) – 0.2 V. With the error amplifiers outputs low, the low-side MOSFET
turn-on within approximately 150ns. The low side MOSFET will remain low until the over voltage fault condition
latch cleared.
