The LT8471 is a dual PWM DC/DC converter containing two internal 2A, 50V switches and an additional 500mA switch to facilitate step-down and inverting conversion. Each 2A channel can be independently configured as a buck, boost, SEPIC, flyback or inverting converter. Capable of generating positive and negative outputs from a single input rail, the LT8471 is ideal for many local power supply designs.The LT8471 has an adjustable oscillator, set by a resistor placed from the RT pin to ground. Additionally, the LT8471 can be synchronized to an external clock. The free running or synchronized switching frequency range of the part can be set between 100kHz and 2MHz.Additional features such as frequency foldback, soft-start, and power good are integrated. The LT8471 is available in 20-lead TSSOP and 28-Lead (4mm × 5mm) QFN packages.

DC1854A is a dual output buck and inverting converter. It provides 5V and –5V power from 6V to 32V input. The 5V output can source up to 1.4A load current and the –5V output can source up to 800mA load current. See the load current versus input voltage figures inside this demo manual for more information. The internal skyhook supply is used to provide voltage to the internal npn switch and can be used for various topologies. Although they are assembled as a single inductor buck and a single inductor inverting converter on DC1854A, the two DC/DC converters can be altered for different topologies. The LT®8471 is a dual PWM DC/DC converter containing two internal 2A, 50V switches and an additional 500mA switch to facilitate step-down and inverting conversion. Each 2A channel can be independently configured as a buck, boost, SEPIC, flyback or inverting converter. Capable of generating positive and negative outputs from a single input rail, the LT8471 is ideal for many local power supply designs. Performance Summary
