OPERATIOU
Short-Circuit/Thermal Protection
The LTC3026 has built-in output short-circuit current
limiting as well as over temperature protection. During
short-circuit conditions, internal circuitry automatically
limits the output current to approximately 3A. At higher
temperatures, or in cases where internal power dissipa-
tion cause excessive self heating on-chip, the thermal
shutdown circuitry will shut down the boost converter and
LDO when the junction temperature exceeds approxi-
mately 150
°
C. It will reenable the converter and LDO once
the junction temperature drops back to approximately
140
°
C. The LTC3026 will cycle in and out of thermal
shutdown without latch-up or damage until the overstress
condition is removed. Long term overstress (T
J
> 125
°
C)
should be avoided as it can degrade the performance or
shorten the life of the part.
Reverse Input Current Protection
The LTC3026 features reverse input current protection to
limit current draw from any supplementary power source
at the output. Figure 6 shows the reverse output current
limit for constant input and output voltages cases. Note:
Positive input current represents current flowing into the
V
IN
pin of LTC3026.
With V
OUT
held at or below the output regulation voltage
and V
IN
varied, IN current flow will follow Figure 6’s
curves. I
IN
reverse current ramps up to about 16
μ
A as the
V
IN
approaches V
OUT
. Reverse input current will spike up
as V
IN
approaches within about 30mV of V
OUT
as the
reverse current protection circuitry is disabled and normal
operation resumes. As V
IN
transitions above V
OUT
the
reverse current transitions into short circuit current as
long as V
OUT
is held below the regulation voltage.
