ELECTRICAL CHARACTERISTICS (continued)
(VCC = VUVEN = 14V, CREG1 = 1µF, CREG2 = 1µF, CCLMP = 0.1µF, RT = 25kΩ, TA = TJ = -40°C to +125°C, unless otherwise noted.
Typical specifications are at TA = +25°C.)
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: VCLMPTH determines the voltage required to operate the current-sense amplifier. The DIM driver requires 2.5V for (VCLMP - VLO)
to drive the external MOSFET. VHI is typically one diode drop above VCLMP. A large capacitor connected to VCLMP 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
(VCC = VUVEN = 14V, CREG1 = 1µF, CREG2 = 10µF, CCLMP = 0.1µF, RT = 25kΩ, RCS = 0.1Ω, TA = +25°C, unless otherwise noted.)
