Description for the LM3410XBSTOVPEV
This evaluation board showcases the LM3410X as a boost LED driver. It is designed to drive four, on-board LEDs (VOUT = 11.4V) in series at an average LED current (ILED) of 190mA. The circuit can accept an input voltage of 3.3V-5.5V. The switching frequency of the LM3410X converter is 1.6MHz allowing the use of small surface mount inductors and chip capacitors. This evaluation board also features the PWM capability of the LM3410 by enabling the user to apply a periodic pulse signal to the DIM terminal of varying duty cycle. This is a 2-layer board using the bottom layer as a ground plane. The above restrictions for the input voltage are valid only for this evaluation board.
