LT1372IS8#PBF

Overview

The LT1372IS8#PBF is a monolithic high-frequency switching regulator manufactured by Analog Devices Inc., housed in an 8-SOIC package. It operates with an input voltage range of 2.7V to 30V and provides an adjustable output voltage starting from 1.245V up to 35V. The device supports a switch current of 1.5A and functions at a fixed switching frequency of 500kHz. It features a quiescent current of 4mA and is rated for operation between -40°C and +125°C.

Feature Summary

• Supports multiple standard switching topologies including boost, buck, Cuk, flyback, forward, and inverting configurations within a single IC.
• Integrates a 1.5A high-efficiency power switch along with complete oscillator, control, and protection circuitry on the die.
• Enables positive or negative output configurations with adjustable voltage regulation capabilities.

Applications

• Lithium-ion battery powered systems requiring SEPIC conversion
• General DC-DC step-up and step-down power supply designs
• Inverting voltage converter circuits

Procurement Notes

Verify the specific suffix IS8 corresponds to the 8-SOIC surface mount package when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure the part number matches the exact pinout and thermal requirements for your PCB layout design before finalizing procurement orders.

Selection Notes

Select this component for designs requiring versatile topology support without external controller complexity. The integrated 1.5A switch suits moderate load applications. Consider the 500kHz frequency for balancing component size and efficiency. Verify that the 8-SOIC package fits your spatial constraints and thermal management strategy.

Part Context

This part belongs to the LT1372 series of high-frequency switching regulators from Analog Devices. It shares core functional architecture with other variants like the LT1372HVIN8#PBF but differs in packaging and temperature grade specifications. The series is designed for compact, efficient power conversion solutions.

Replacement Considerations

LT1372HVIN8#PBF offers similar electrical performance in a PDIP-8 through-hole package. LT1372CN8#PBF provides comparable functionality in a commercial temperature grade PDIP-8 package. Verify pin compatibility and thermal characteristics when substituting.
