Description

The STLD41 is a boost converter that operates

from 3.0 V to 21 V and can provide an output

voltage as high as 38 V. It can drive up to 40 white

LEDs connected in 4 strings of 10 LEDs in series.

The total output current capability is 120 mA at an

output voltage of 38 V. Regulation is performed by

the internal error amplifier which works with the

feedback voltage from the sensing resistor. The

device can be turned ON/OFF by way of the logic

signal connected to the EN pin. The LEDs can be

dimmed by applying a PWM signal to the PWM

pin.
