LT1074HVCT in Linear Tech / ADI LT Series Family
The LT1074HVCT is a high-voltage monolithic bipolar switching regulator family developed by Linear Technology, now part of Analog Devices. Designed for power conversion, these 5A step-down regulators are capable of operating with input voltages up to 60V, making them suitable for high-voltage industrial and telecommunications applications. The family integrates a 100kHz oscillator, current limit circuitry, and a high-efficiency power switch on a single silicon die, simplifying the design of robust buck, inverting, and flyback converter topologies.
Variants in This Sub-Family
Variants within the LT1074HVCT sub-family primarily differ based on their thermal packaging and lead-free status, denoted by the #PBF suffix. While the core LT1074HV architecture supports up to 60V, standard LT1074 versions are limited to 45V. Packaging options like the TO-220-5 (T) provide varying thermal resistance ratings, impacting the maximum sustainable current in high-temperature environments or compact enclosures without active cooling.
