Application Information (Continued)
Thermal-Overload Protection
The
FP6783
boost
converter
provides
Thermal-overload Protection to prevent excessive
power dissipation from overheating the IC. When the
junction temperature exceeds Tj=150°C, a thermal
sensor activates the fault protection, which shuts
down (latches) all outputs. The thermal sensor turns
internal circuitry on again after IC cycle the input
voltage to clear the thermal shutdown latch.

Output Fault Protection
During steady-state operation, if feedback voltage
of the main regulator falls below 1.0V, positive
linear regulator falls below 1.0V or negative linear
regulator falls below 450mV, the FP6783 activates
an internal fault timer. If any condition indicates a
continuous fault for the fault timer duration (160ms
typ.) the IC sets the fault latch to shut down all its
output. Once the fault condition is removed, cycle
the VIN (below the UVLO falling threshold) to clear
the fault latch and reactivate the device. The
fault-detection
circuit
is
disabled
during
the
soft-start ramp.
Over Current Protection
The FP6783 has Over-Current Protection (OCP)
that limits the peak inductor current in every
switching cycle. It prevents large current from
damaging the inductor and diode. Once the
inductor current exceeds the current limit, the
internal switch turns off immediately and shortens
the duty cycle. The output voltage drops if the
over-current condition occurs. Current limit is
affected by the input voltage, duty cycle, and
inductor value.
