LT8582IDKD#TRPBF

The LT8582IDKD#TRPBF is a versatile dual-channel PWM DC/DC converter from Analog Devices, designed for local power supply applications. Each channel features a 42V switch, and they can be tied together for a total current limit of 3A. The device supports a wide input voltage range from 2.5V to 22V, with a maximum transient of 40V.

Each channel can be configured as a boost, SEPIC, inverting, or flyback converter, offering flexibility for various power designs. The LT8582 includes fault protection against input overvoltage and overtemperature conditions, along with output short-circuit protection. It operates with a switching frequency up to 2.5MHz and is available in a 24-pin 7mm x 4mm DFN package.

Key features include a power good pin for event-based sequencing, adjustable undervoltage lockout, and a high gain SHDN pin that accepts slowly varying input signals. The integrated master/slave switch design allows for efficient power conversion, with a low switch saturation voltage of 270mV at 2.75A typical.

This component is suitable for applications such as vacuum fluorescent display bias supplies, TFT-LCD bias supplies, and automotive engine control unit power. Its dual output capability allows for configurations like 12V and -12V from a 5V input, providing up to 14.4W of combined output power.
