QUICK START GUIDE FOR DEMONSTRATION CIRCUIT DC915

LT3466EDD-1

DESCRIPTION

Demonstration circuit DC915 features LT3466-1

high efficiency white LED driver and step-up con-

verter. There is one LED driver output for 8

WLEDs and 2 normal outputs for LCD. VO1

drives 8 LEDs in series with 15mA LED current

and VO2/VO3 can delivery +/- 15V at 10mA cur-

rent. If the charge-pump circuitry (C4, C5 and D1),

which generates VO3, is removed, VO2 can de-

liver over 35mA of current. The input voltage

range is 3V to 14V, which can go as low as 2.7V

with slightly reduced output current.

Each output channel has a jumper (JP1 or JP2)

for enabling the output(s) and a CTRL pin (CTRL1

or CTRL2) for LED brightness (current) control or

VO2/VO3 voltage adjustment. Placing the jump-

ers to “/SD” turns off the WLEDs or VO2/VO3, and

jumpers to “EN” enables the selected channel of

the LT3466-1. Modulating the voltage at CTRL1

or CTRL2 pin respectively can change the LED

current at VO1 or VO2/VO3 voltages. As the volt-

age on the CTRL1 pin increases from 0V to 1.6V,

the feedback voltage across the LED current pro-

gramming resistor increases from 0 to 200mV,

varying the LED current from 0 to 15mA. Simi-

larly, VO2/VO3 voltages increase with voltage on

CNTL2. The “CTRL to FB” curves are show in the

datasheet.

JP3 can conveniently set 8 WLEDs (JP3 jumper at

top position), 6 WLEDs (JP3 jumper at bottom po-

sition), or open circuit protection test (no jumper),

while FB1 terminal monitors the WLED current

(VFB1/R1).

The overall solution occupies less than 1.62 cm

with components on one side of the PCB.
