Description

This evaluation board is based on the STLD40D

that is a boost converter that operates from 3.0 V

to 5.5 V and can provide an output voltage as 37 V

and can drive up to 10 white LEDs in series. The

converter is a PFM (pulse frequency modulation)

inductor switches and can work in discontinuous

(DCM) mode operation. A minimum OFF time of

the embedded boost switch TSW is fixed

internally and allows limiting the switching

frequency. The output current capability is 20 mA

with an output voltage of 37 V. The regulation is

done by sensing the led current through the

resistor R

through the logic enable signal pin EN. Applying a

low frequency PWM signal the LEDs can be

dimmed. The maximum peak inductor current can

be programmed.
