DESCRIPTION

LT3590

48V Buck-Mode LED Driver

Demonstration circuit 1166A is a 48V Buck-Mode LED

Driver featuring the LT

3590. The LT3590 is a fixed fre-

quency buck-mode converter specifically designed todrive

up to 10 LEDs in series from a 48V DC source. Series con-

nection of the LEDs provides identical LEDcurrents of up to

50mA, resulting in uniform brightness and eliminating the

need for ballast resistors. A fixed frequency current mode

architecture results in stable operation over a wide range

of input voltage and load condition. The high switching

frequency allows using tiny components for the circuit.

QUICK START PROCEDURE

Demonstration circuit 1166A is easy to set up to evalu-

ate the performance of the LT3590. Refer to Figure 1 for

proper measurement equipment setup and follow the

procedure below:

1. Place jumpers in the following positions:

JP1 ON

2. With power off, connect the input power supply to VIN

and GND.

3. With power off, connect LEDs to LED+ and LED–.

4. Turn on the power at the input.

NOTE: Make sure that the input voltage does not

exceed 55V.

5. Check for the proper output voltage and current.
