be used as a remote ON/OFF and a synchronization input in
both modes. Please refer to Table 3 for possible combinations
of the functions with example circuits shown in Figure 30
through Figure 40. A description of speci?c functions in terms
of the MULTI-FUNCTION pin I/V characteristic is shown in
Figure 11. The horizontal axis represents MULTI-FUNCTION
pin current with positive polarity indicating currents ?owing into
the pin. The meaning of the vertical axes varies with functions.
For those that control the ON/OFF states of the output such
as UV, OV and remote ON/OFF, the vertical axis represents
the enable/disable states of the output. UV triggers at I UV
(+50 μ A typical) and OV triggers at I OV (+225 μ A typical with
30 μ A hysteresis). Between the UV and OV thresholds, the
output is enabled. For external current limit and line feed-
forward with DC MAX reduction, the vertical axis represents the
magnitude of the I LIMIT and DC MAX . Line feed-forward with
DC MAX reduction lowers maximum duty cycle from 78% at I M(DC)
(+60 μ A typical) to 38% at I OV (+225 μ A). External current
limit is available only with negative MULTI-FUNCTION
pin current. Please see graphs in the Typical Performance
Characteristics section for the current limit programming
range and the selection of appropriate resistor value.
