FUNCTION
Drain of the Internal Switching MOSFET
Input. Connect to LED string anode in boost and buck-boost configuration to get OVP protection
during open LED. Bypass it with a sufficient capacitor not to allow IN to go below 6.5V in buck
applications.
Base Drive for External Bipolar Until Internal Driver Starts Switching for the First Time After Power-Up
Compensation Component Connection for the Switching Stage. Connect a suitable RC network to
ground. This is the output of the g m amplifier
Analog Dimming and Thermal Foldback. The IC sources 50μA current out of this pin. Whenever this
pin voltage is > 1.2V, the FB voltage is regulated to internal 200mV reference. Whenever this pin
voltage < 1.2V, the FB voltage is regulated to V REFI /6. Leave this pin unconnected to disable this
foldback feature.
Ground
Current-Sense. This pin includes a 5k I /4pF RC filter at its input to average the current information
over the switching cycle. Connect this pin directly to SOURCE.
Source of the Internal Switching MOSFET
Exposed Pad. Connect EP to the ground plane for heatsinking. Do not use the EP as the only
electrical connection to ground.
