LT1074HVCT7#PBF

Overview

The LT1074HVCT7#PBF is a high-voltage monolithic bipolar switching regulator manufactured by Analog Devices Inc. It operates in a buck, boost, or flyback topology with an adjustable output voltage ranging from 2.5 V to 35 V. The device supports a maximum switch current of 5.5 A and accepts an input voltage between 8 V and 64 V. It features a fixed switching frequency of 100 kHz and includes integrated power switches, oscillator, control circuitry, and current limit components. Packaged in a TO-220-7 through-hole case, it functions within a temperature range of 0°C to 70°C.

Feature Summary

Integrates power switch, oscillator, and control circuitry for minimal external component requirements
Supports multiple topologies including buck, boost, and flyback configurations
Includes internal current limiting protection mechanisms

Applications

Positive-to-negative converter circuits
Tapped-inductor buck converter designs
General step-down DC-DC conversion applications

Procurement Notes

Verify the specific suffix HVCT7 against official Analog Devices documentation to confirm high-voltage rating and package type. Confirm RoHS compliance status via the manufacturer's material declaration. Check current availability as distribution channels may list limited stock or special orders. Ensure the TO-220-7 form leads match your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when high input voltage up to 64 V is required alongside substantial output current capability. The adjustable output allows flexibility for various load requirements. Consider the thermal performance of the TO-220-7 package for heat dissipation needs. Verify that the 100 kHz switching frequency aligns with your electromagnetic interference constraints and inductor size preferences.

Part Context

This part belongs to the LT1074 series of monolithic bipolar switching regulators. These devices are designed to simplify power supply design by integrating most necessary control functions on a single chip. The series offers robust performance for industrial and commercial power management applications requiring reliable DC-DC conversion.
