Product Overview

The LT8582IDKD#PBF is a dual independent channel PWM DC/DC Converter with a power good pin and built-in fault protection to help guard against input overvoltage and overtemperature conditions. Each channel consists of a 42V master switch and a 42V slave switch that can be tied together for a total current limit of 3A. The LT8582 is ideal for many local power supply designs. Each channel can be easily configured in boost, SEPIC, inverting or flyback configurations. Together, the two channels can produce a 12V and a -12V output with 14.4W of combined output power from a 5V input. In addition, the LT8582's slave switch allows the part to be configured in high voltage, high power charge pump topologies that are more efficient and require fewer components than traditional circuits. It also features innovative SHDN pin circuitry that allows for slowly varying input signals and an adjustable undervoltage lockout function.
  • Power good pin for event based sequencing
  • Each channel easily configurable as a boost, SEPIC, inverting or flyback converter
  • Can be synchronized to an external clock
  • Output short-circuit protection
  • High gain SHDN pin accepts slowly varying input signals
