Adjust input
? Leave floating, or connect to VREF to set 100% output current.
? Drive with dc voltage. (50mV<VADJ< VREF) to adjust output
current from 10% to 100% of set value. (DC brightness control
mode)
? Drive with low frequency (200Hz) PWM control signal to gate
output ‘on’ and ‘off’ at the PWM frequency. (PWM brightness
control mode)
? Drive with low level dc voltage (VADJ<28mV) to turn off device
(Standby mode)
Bias pin for setting base current of internal switch transistor
? Short pin to ground to define maximum base drive current for
output switch (Maximum output current condition)
? Connect resistor (R BIAS ) from this pin to ground to reduce base
drive current (Reduced output current condition)
Compensation point
? Connect 10nF capacitor from this pin to ground to provide loop
compensation
No connection to this pin (open circuit)
Switch peak current sense pin
? Connect resistor (R SENSE ) from this pin to ground to define peak
switch current (ISW PEAK )=V SENSE /R SENSE
Switch emitters (connect both pins to top of R SENSE to sense emitter current)
Switch collectors (connect both pins to lower side of coil)
Load side input of high side current monitor
Input supply to high side current monitor
? Connect to output voltage (cathode of Schottky)
? Connect resistor (R M ) between M_LOAD and M_VIN to define
nominal average output (LED) current of 0.1/R M
Positive supply to device (1.2-12V)
? Decouple to ground with capacitor close to device
Temperature adjust input for LED thermal compensation
? Connect thermistor/resistor network to this pin to reduce output
current above a preset temperature threshold.
? Connect to VREF to disable thermal compensation function
(see section on temperature control for details)
Internal 0.5V reference voltage output
Connect to ground (0V)
