LT1372IN8#PBF

Overview

The LT1372IN8#PBF is a monolithic high-frequency switching regulator manufactured by Analog Devices Inc. It operates within an input voltage range of 2.7V to 30V and delivers a switch current of 1.5A. The device features a fixed switching frequency of 500kHz and supports adjustable output voltages starting from 1.245V. It is housed in an 8-SOIC package with a wide operating temperature range of -40°C to +125°C.

Feature Summary

Supports multiple standard switching topologies including boost, buck, Cuk, flyback, forward, and inverting configurations.
Integrates a 1.5A high-efficiency power switch along with complete oscillator, control, and protection circuitry on a single die.

Applications

Low ripple negative voltage generation using Cuk converter topology
Space-constrained systems requiring small external inductors due to high-frequency operation
Battery-powered applications utilizing SEPIC or boost topologies for variable input sources

Procurement Notes

Verify the specific suffix IN8 corresponds to the industrial temperature grade and SOIC-8 package configuration required for your design. Confirm RoHS compliance status through official manufacturer documentation prior to finalizing procurement orders. Ensure compatibility with existing PCB footprints and thermal management strategies for the selected application environment.

Selection Notes

Select this component when a versatile single-chip solution is needed for various DC-DC conversion topologies without external power switches. The integrated 1.5A switch capability suits moderate power applications where board space is limited. Consider the 500kHz frequency trade-off between component size and electromagnetic interference requirements for your specific system constraints.

Part Context

This part belongs to the LT1372 family of high-efficiency switching regulators designed for flexibility in power supply architectures. Unlike linear regulators, it offers higher efficiency across wide input-output differentials. The IN8 designation indicates the industrial temperature range variant packaged in a standard surface-mount format suitable for automated assembly processes.
