The LT®8582 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. 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. Additional features such as output short protection, frequency foldback and soft-start are integrated. The LT8582 is available in a 24-pin 7mm × 4mm DFN package.
