PRODUCTION DATA
Typical Buck LED Driver Application Schematic shows that the undervoltage protection threshold is programmed using a resistor divider, RUV1 and RUV2, from the input voltage, VIN to PGND. Use Equation 23 and Equation 24 to calculate the resistor values.
A capacitor of 1 nF from UDIM pin to GND is placed close to device to improve noise immunity.
