Analog Devices Inc. LT8471 Dual Multitopology DC/DC Converters
Analog Devices Inc. LT8471 Dual Multitopology DC/DC Converters contain two internal 2A, 50V switches, and an additional 500mA switch to facilitate step-down and inverting conversion. The LT8471 from Analog Devices has a 2A channel that can be independently configured as a buck, boost, SEPIC, flyback, or inverting converter. The converters are capable of generating positive and negative outputs from a single input rail. The LT8471 is ideal for many local power supply designs.
