Note 1: Dropout voltage is defined as the input to output differential voltage at which the regulator output voltage drops 100mV below
the nominal output voltage.
Note 2: V CLMPTH determines the voltage required to operate the current-sense amplifier. The DIM driver requires 2.5V for (V CLMP - V LO )
to drive the external MOSFET. V HI is typically one diode drop above V CLMP . A large capacitor connected to V CLMP slows the
response of the LED current-sense circuitry, resulting in current overshoot. To ensure proper operation, connect a 0.1μF
capacitor from CLMP to LO.
Typical Operating Characteristics
