  • 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 RLED. The device can be turned ON/OFF 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.

    Key Features

    • Low shutdown current <1 μA
    • Enable pin with possibility of PWM dimming control
    • Inductor switches boost controller
    • High efficiency over wide range of input voltage from 3.0 V to 5.5 V
    • PFM mode control
    • Adjustable peak current limit
    • Over-voltage protection with automatic restart
