Description

Configures second stage series/parallel output channel configuration.

[7]

STRING

0 = Second stage configured as parallel strings

1 = Second stage configured with strings in series

[ 6:5 ]

Configures the maximum measurable second stage switching cycle period.

00 = 51.15s

TT_MAX[1:0]

01 = 102.35s

10 = 153.55s

11 = 204.75s

Configures which channel is connected to the color LED string (the string with a

[4]

LED_ARG

gain that is dependent on dim and temperature).

0 = Color LED string connected to channel 1

1 = Color LED string connected to channel 2

[ 3:1 ]

IPEAK[2:0]

Configures the minimum measurable peak current level on the second stage

sense resistor when the gate drive is turned on along with the CLAMP[1:0] set-

ting. IPEAK[2:0] is an unsigned integer in the range of 0value7. The voltage

on the FBSENSE pin that corresponds to the minimum peak current is calcu-

lated using the following formula:
