STLD41:White LED driver for mid-size LCD display backlight

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.
