Note 1: All devices are 100% tested at T A = +85°C. All limits over temperature are guaranteed by characterization.
Note 2: V REF is measured with DIM/FB connected to the COMP pin (see the Functional Diagram ).
Note 3: The MAX16801 is intended for use in universal input offline drivers. The internal clamp circuit is used to prevent the boot-
strap capacitor (C1 in Figure 5) from charging to a voltage beyond the absolute maximum rating of the device when
EN/UVLO is low. The maximum current to IN (hence to clamp) when UVLO is low (device in shutdown), must be externally
limited to 2mA (max). Clamp currents higher than 2mA may result in clamp voltage higher than +30V, thus exceeding the
absolute maximum rating for IN. For the MAX16802, do not exceed the +24V maximum operating voltage of the device.
