Overview

The LM3435 Evaluation Board has been designed for evaluating the performance of the device in a typical pico projector application. The end user can interface his own system to the evaluation board to test out the performance of the system. With LM3435, the system requires only single DC-DC converter to drive three color LEDs instead of using three DC-DC converters with conventional design. The suggested approach not only saves components cost, but also releases invaluable PCB space to the system and enhances system reliability. Assuming the handy projector is powered by a single lithium battery cell or a 5 VDC wall mount adaptor, the key specifications of the evaluation board are as in below:

  • Supply voltage range, VIN = 2.7V to 5.5V
  • Preset LED current per channel, ILED = 1.5A
  • Minimum LED current per channel, ILED (min) = 600 mA
  • Maximum LED forward voltage drop, VLED = 3.5V @ 1.5A
  • Flyback converter switching frequency, FSW = approx. 500 kHz
