LTC3789EGN in Linear Tech / ADI LT Series Family
The LTC3789EGN family, manufactured by Analog Devices (Linear Technology), represents a high-performance buck-boost switching regulator controller designed for wide input voltage ranges. It utilizes a current mode architecture to provide efficient power conversion where the input voltage may be higher, lower, or equal to the output voltage. This family is highly regarded for its synchronous rectified operation, which maximizes efficiency in demanding industrial and automotive power delivery systems where stable 4-switch regulation is critical.
Variants in This Sub-Family
Variants within the LTC3789 sub-family primarily differ based on their thermal grade and package lead finishes. The 'E' designation specifies an extended temperature range of -40 to 125 degrees Celsius, while the 'GN' suffix identifies the 28-lead SSOP package. Specific part numbers like #PBF denote lead-free, RoHS-compliant finishing, whereas others may offer different tape-and-reel quantities or alternative lead-frame materials for specific assembly requirements.
