Description

  • LM3508TLEV, Evaluation Board using LM3508 a synchronous step-up DC/DC converter designed for white LED applications. The evaluation board is set up to drive 4 standard VF white LEDs from a 2.7V to 5.5V input supply. A fifth LED can be placed across the R1 pad for testing up to five low VF LEDs. The LED current is set using the RSET resistor via the equation ILED = 0.2V/RSET. The evaluation board comes with RSET = 10 O for approximately 20 mA LED current

Key Features
