Overview
The LT1074HVCT7#06PBF is a high-voltage switching regulator IC from Analog Devices, housed in a TO-220-7 package. It supports Buck, Boost, and Flyback topologies with adjustable output voltage ranging from 2.5V to 35V. The device delivers a switch current of 5.5A at a fixed switching frequency of 100kHz. It operates on an input voltage range of 8V to 64V and functions within a temperature range of 0°C to 70°C.
Feature Summary
- Integrates power switch, oscillator, control circuitry, and current limit components for minimal external part count
- Supports multiple DC-DC conversion topologies including buck, boost, and flyback configurations
- Capable of generating positive or negative adjustable output voltages
Applications
- Positive-to-negative converter circuits
- Negative boost converter designs
- General-purpose DC-DC step-down regulation
Procurement Notes
Verify the specific suffix #06PBF against the manufacturer datasheet to confirm pinout and packaging details. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure thermal management requirements are met for the TO-220-7 package during operation.
Selection Notes
Select this component when high input voltage up to 64V is required alongside substantial output current capability. The integrated bipolar design simplifies layout by reducing external component count compared to discrete solutions. Verify that the operating temperature range of 0°C to 70°C aligns with the application environment.
Part Context
This part belongs to the LT1074 family of monolithic bipolar switching regulators. It shares core architecture with variants like LT1074IT7#PBF but differs in voltage ratings and package configuration. The HV designation indicates enhanced high-voltage handling capabilities suitable for industrial power supplies.
Replacement Considerations
LT1074HVCT#06PBF is a non-tape variant of the same electrical specification. LT1074IT7#PBF offers similar functionality but with different voltage and package characteristics requiring schematic review.
