APPLICATIO

Short-Circuit Protection
When the output is shorted to ground, the LTC1502-3.3
will continuously charge the C2 capacitor up to approxi-
mately 1.4 times V
IN
, and then discharge C2 into the
shorted output. Since the discharging of C2 into V
OUT
will
bring the C2 voltage below the COMP2 start-up compara-
tor trip voltage, the output charge pump will be forced
Hi-Z while C2 charges up again. Hence, the internal charge
W
U
U
pump gate drive voltage is limited to (1.4)(V
IN(MAX)
) on the
C2 pin, and no continuous current is supplied to V
OUT
. The
resulting output short-circuit current is limited to under
20mA (typ) thereby allowing the LTC1502-3.3 to endure
an indefinite output short circuit without damage. When
the short is removed, the part will start up, and operate
normally.
