decrease the output current to the lamp for decreasing the output power. The speed of
the constant power control loop is set by the value of the CPCOMP at the PCOMP pin
that determines how fast the loop will react and adjust the buck on-time over the
changing load conditions.
5.7 Current Limitation Control
The constant power control loop will increase or decrease the buck current for
maintaining constant power in the lamp load. During lamp warm-up, the lamp voltage
can be very low (20V typical) and the constant power loop will attempt to increase the
buck current to several amps of current to maintain constant power. This high current
can exceed the manufacturer’s maximum current rating for the HID lamp. To prevent
this condition, an additional current limitation control loop has been included in the IC
Should the voltage at the ISENSE pin exceed the voltage level at the OC pin, another
OTA will sink current from the ICOMP pin. When the ICOMP pin voltage decreases
below the PCOMP pin voltage, then the current limitation loop will override the constant
power loop and the ICOMP pin will decrease the buck on-time. The lower of the
PCOMP or ICOMP pins will override the other and control the buck on-time. When the
lamp eventually warms up and the lamp voltage increases to a level where the lamp
current is below the maximum allowable limit, then the ICOMP pin voltage will increase
above the PCOMP pin voltage, and the PCOMP pin will control the buck on-time again
for maintaining constant power.
5.8 Buck OFF Mode
The IC will enter the Buck-OFF Mode if any one of these 3 conditions occur:
?
?
?
VSENSE > VOV or
PCOMP < 0.2V or
ICOMP < 0.2V
When in the Buck-OFF Mode, the IC will go back to General Mode if all of these 3
conditions are valid:
?
?
?
VSENSE < VOV (2/5) and
PCOMP > 0.2V and
ICOMP > 0.5V
The IC will instead go back to Ignition Mode if all of these 3 conditions are valid:
?
?
?
VOV(2/5) < VSENSE < VOV
PCOMP > 0.2V
ICOMP > 0.5V
