Product Overview

The LT8471IFE#PBF is a dual multi-topology DC/DC Converter with two internal 2A 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 fold back, soft-start and power good are integrated.
  • Dual 2A and one 500mA, 50V internal power switch channels
  • 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
