Description
Adjust input
? Leave floating, or connect to V REF to set 100% output current.
? Drive with dc voltage. (50mV<V ADJ < V REF ) 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 (V ADJ <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)
Control input/output for feedback control loop
? Connect 10nF capacitor from this pin to ground to provide loop compensation
Not connected internally (Open circuit)
Switch peak current sense pin
? Connect resistor (R SENSE ) from this pin to ground to define peak switch current
(I SWPEAK )=0.05/R S
Switch emitters (Connect both pins to top of RSENSE to sense emitter current)
Switch Collectors (Connect both pins to lower side of coil)
Internally connected - Do not connect to external circuitry
Input supply to high side current monitor
? Connect output voltage (whichever is higher)
? Connect resistor (R M ) from this pin to to V IN to define nominal average output (LED)
current of 0.1/R M
Input supply voltage and load side input of high side current monitor.
Connect to sensing resistor RM.
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 V REF to disable thermal compensation function
(see section on temperature control for details)
Internal 0.5V reference voltage output
Connect to ground (0V)
