LT1370HVCT7#PBF

Overview

The LT1370HVCT7#PBF is a high-efficiency, high-frequency current-mode switching regulator manufactured by Analog Devices Inc. It supports multiple topologies including Boost, Buck, Cuk, Flyback, Forward, and Inverting configurations. The device operates with an input voltage range of 2.7 V to 30 V and delivers a maximum output current of 6 A. It features a fixed switching frequency of 500 kHz and adjustable output voltage. The component is housed in a TO-220-7 through-hole package and includes a shutdown function. It operates within a temperature range of -40°C to +125°C and draws a quiescent current of 4.5 mA.

Feature Summary

• Supports versatile circuit topologies such as boost, buck, cuk, flyback, forward, and inverting configurations for flexible power design.
• Delivers high output current capability up to 6 A with high efficiency at a 500 kHz switching frequency.
• Includes a dedicated shutdown pin for power management control.

Applications

• Industrial power supply systems requiring wide input voltage ranges
• Battery-powered equipment utilizing boost or buck converter stages
• Telecommunications infrastructure power modules
• Embedded systems needing isolated or non-isolated DC-DC conversion

Procurement Notes

Verify the specific suffix CT7 corresponds to the TO-220-7 through-hole package variant when sourcing. Confirm that the HV designation aligns with the required 30 V maximum input voltage specification for your application. Ensure compatibility with the 500 kHz switching frequency regarding external inductor and capacitor selection. Cross-reference the manufacturer datasheet for thermal performance requirements associated with the 6 A output current in the selected enclosure.

Selection Notes

Select this component when a single IC must support multiple converter topologies like buck, boost, or inverting architectures. It is suitable for designs requiring a wide input voltage range extending up to 30 V. Consider this part for applications demanding high output current up to 6 A with efficient operation. The through-hole TO-220-7 package is appropriate for designs prioritizing robust thermal dissipation over compact surface-mount footprints.

Part Context

This part belongs to the LT1370 series of high-frequency switching regulators from Analog Devices. The series is characterized by its ability to implement various standard DC-DC converter topologies using a single controller chip. The LT1370HV variant specifically addresses higher input voltage requirements compared to standard versions. It serves as a core component in power management integrated circuits (PMIC) designed for industrial and commercial applications.

Replacement Considerations

LT1370CT7#PBF is a parameter-equivalent alternative differing primarily in the specified operating temperature range.
