TLE 4241 GM
Circuit Description
Figure 1
Block Diagram
An internal reference voltage of typ. 1.20 V supplies the REF pin which is connected to
GND via an external resistor. In the SET = H mode the reference current flowing on the
REF pin is mirrored with an amplification to form the desired output current. The typ.
output current in the SET = H mode calculates:
(1)
The output current is shown as a function of the reference resistance on
Page 10
for the
high as well as for the low current mode.
With the PWM input the LED brightness can be regulated via duty cycle. Also PWM = L
sets the TLE 4241 in sleep mode resulting in a very low current consumption of << 1

typ. Due to the high impedance of the PWM input (see timing diagram

versus

) the PWM pin can thus also be used as an Enable input.
