Description

  • DC2404A, Demonstration Circuit is a 36V synchronous buck-boost LED driver featuring the LT3942. It drives a single string of LEDs up to 14V at 1A when VIN is between 9V and 36V and will run down to 3VIN with reduced ILED. DC2404A runs at 2MHz switching frequency with spread spectrum frequency modulation (SSFM) disabled. When enabled, SSFM spreads the switching frequency of the LT3942 from fSW to fSW + 25% for reduced EMI performance. The LT3942 has an operating input voltage range of 3V to 36V. It has internal, synchronous 40V switches for high efficiency and small size. It has an adjustable switching frequency between 300kHz and 2MHz. The LT3942 can by synchronized to an external source, programmed with SSFM enabled for low EMI, or set to normal operation
