LT1372HVIN8#PBF

Overview

The LT1372HVIN8#PBF is a monolithic high-frequency switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 2.7 V to 30 V and delivers a switch current of 1.5 A. The device supports multiple topologies including boost, buck, Cuk, flyback, forward, and inverting configurations. It features an adjustable output voltage starting at 1.245 V, a fixed switching frequency of 500 kHz, and a quiescent supply current of 4 mA. The component is housed in an 8-pin PDIP package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Supports versatile DC-DC conversion topologies including boost, buck, Cuk, flyback, forward, and inverting circuits.
• Integrates a high-efficiency 1.5 A power switch with complete oscillator, control, and protection circuitry on the die.
• Features a shutdown capability for power management applications.

Applications

• Cuk converter implementations
• Boost and buck regulation circuits
• Flyback and forward converter designs
• Inverting voltage supply generation

Procurement Notes

Verify the specific suffix 'HV' against official Analog Devices documentation to confirm high-voltage variant specifications. Ensure the PDIP-8 through-hole package matches the target PCB footprint. Cross-reference the manufacturer part number LT1372HVIN8#PBF with authorized distributors to validate authenticity and RoHS compliance status before procurement.

Selection Notes

Select this component when a single IC must support multiple standard switching topologies such as Cuk or flyback. The 1.5 A switch current rating suits moderate power applications requiring flexibility. Verify that the 500 kHz fixed frequency aligns with external component size constraints. Confirm the 2.7 V minimum input voltage meets system requirements.

Part Context

This part belongs to the LT1372 series of high-frequency switching regulators from Analog Devices. It shares functional similarities with other variants like the LT1372IS8#PBF but differs in package type and potentially voltage ratings. The series is designed for applications requiring flexible topology support within a compact monolithic solution.

Replacement Considerations

LT1372IN8#PBF is a documented alternative within the same family offering similar functionality in a different package configuration.
