Product Overview

The LT8471EFE#PBF is a dual multitopology DC/DC Converter with 50V/2A switches and an additional 500mA switch to facilitate step-down and inverting conversion and synchronization. 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, it is ideal for many local power supply designs. This converter has an adjustable oscillator, set by a resistor placed from the RT pin to ground. Additionally, this 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.
  • 2A Primary channels can be buck, boost, SEPIC, ZETA, flyback or inverting DC/DC converter
  • 500mA Skyhook channel efficiently generates boosted input voltage
  • Wide input voltage range of 2.6 to 50V
  • UVLO and OVLO Programmable on OV/UV pin
  • Soft-start programmable for each channel
  • Fixed frequency PWM (set by RT pin or synchronized to external clock)
  • Anti-phase switching reduces input ripple
