Description
- DC923A, Demo Board using LT3475 dual step-down 1.5A LED driver in a 16-lead TSSOP thermally enhanced package. Using for driving two 1.5A LEDs on separate channels (one on each channel) from a wide input voltage range. The high switching frequency scheme permits the use of a small inductor and ceramic capacitors to save space and cost. The current mode PWM control scheme provides fast transient response and cycle-by-cycle current limiting. Frequency foldback and thermal shut-down provide additional protection
