Note 1: Power dissipation is 825 mW when mounted. Derate at 6.6 mW/°C for operation above 25 °C.

Note 2: For temperature dependence refer to "Slope Compensation Peak Current vs. Temperature" graph.

Note 3: The UVLO "on" voltage is guaranteed always to be below the internal clamp voltage.

Note 4: Guaranteed by design; not 100% tested.
