POWER MANAGEMENT
There are four methods for setting and adjusting the LED current
outlined here. The methods are:
1) R
SET only
2) Analog Reference V
ADJ
3) NMOS switched parallel resistors
4) PWM Input
Method 1. The most basic means of setting the LED current is
with a resistor connected from ISET to GND, as shown in the
application circuit on Page 1. The resistor R
SET establishes the
reference current needed for a constant LED current. Values of
R
SET for a fixed LED current are given in Table 2 and also in the
below graph, “Typical R
SET Resistance vs. LED Current”. Methods
2 and 3 on page 10 are for setting the LED current allow for
brightness control.
