n 20-Lead TSSOP and 28-Lead QFN Packages 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. n The LT8471 has an adjustable oscillator, set by a resistor
placed from the RT pin to ground. Additionally, the LT8471 …
