Detailed Description
Constant Current Output Value Setting
The output current is determined by resistor value. The resistors connected between RES(G, R)
pin and GND decide the base current output. Fig1. shows the approximate relation between
resistor value and output current value. The resistor should be placed as close to Rext terminal as
possible to avoid the noise influence
Fig.1
Output Current Performance vs. Output Voltage
In order to obtain the good constant current output performance, the minimum output voltage
is necessary.
