Note 1: All devices are 100% production tested at TA = +25 N C. Limits over temperature are guaranteed by design.
Note 2: The MAX17498A is intended for use in universal input power supplies. The internal clamp circuit at IN is used to prevent the
bootstrap capacitor from charging to a voltage beyond the absolute maximum rating of the device when EN/UVLO is low
(shutdown mode). Externally limit the maximum current to IN (hence to clamp) to 2mA (max) when EN/UVLO is low.
