DC3103A

Demonstration circuit DC3103A is a monolithic 4-switch buck-boost voltage regulator featuring the LT®3942. It has been designed with an output voltage set to 12V with capability of delivering up to 1A when the input voltage is between 7V and 36V. The demonstration circuit continues operating with an input voltage as low as 3V with reduced output power capability. DC3103A is configured for 2MHz switching frequency with spread spectrum frequency modulation (SSFM) disabled. When enabled, SSFM adjusts switching frequency of LT3942 between 2MHz and 2.5MHz for improved 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 oscillator source, programmed with SSFM enabled for low EMI or set to normal operation.
