Programmable Switch-Mode LED Driver
with Analog-Controlled PWM Dimming
ELECTRICAL CHARACTERISTICS
Note 1: Dropout voltage is defined as the input to output differential voltage at which the output voltage drops 100mV below its nom-
inal value measured at output.
Note 2: V CLMP_TH determines the voltage necessary to operate the current-sense amplifier. The DIM driver requires 2.5V for (V CLMP
- V LO ) to drive a FET. 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.
Note 3: Minimum pulse width required to guarantee proper dimming operation.
Note 4: FAULT multiplexes a programming interface and fault indication functionality. At power-up initialization, an internal timer
enables FAULT and two programming passcodes must be entered within the programming slot to enter programming
mode. If the programming passcodes are not received correctly within the programming slot, FAULT goes back towards
fault indication. Cycling power to the device is required to re-attempt entry into programming mode.
Note 5: Not production tested. Guaranteed by design.
Note 6: Recovery time is the time required for FAULT to be pulled high by the internal 10k Ω resistor.
Typical Operating Characteristics
(V CC = V UVEN = 14V, C REG1 = 1μF, C REG2 = 10μF, C CLMP = 0.1μF, R CS = 0.1 Ω , Binning adjustment register is ‘0000’, T A = +25°C,
unless otherwise noted.)
