LT1509ISW#PBF

Overview

The LT1509ISW#PBF is a power factor and PWM controller manufactured by Analog Devices Inc. It integrates power factor correction and pulse width modulation control functions within a single integrated circuit. The device utilizes an 8-SOIC package with a width of 0.295 inches (7.50 mm). It operates across the industrial temperature range, supporting applications requiring combined PFC and PWM regulation strategies for efficient power conversion systems.

Feature Summary

• Integrates power factor correction and PWM control functions
• Supports combined PFC and PWM regulation strategies
• Designed for industrial temperature range operation

Applications

• Power factor correction circuits
• PWM controlled power supplies
• Combined PFC and PWM power conversion systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific package markings against official datasheets. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly. Validate supplier documentation matches the exact part number suffixes.

Selection Notes

Select this component when a single IC solution for both power factor correction and PWM control is required. Consider the 8-SOIC package constraints for PCB layout. Evaluate thermal performance within the specified industrial temperature range. Compare against discrete solutions if separate PFC and PWM controllers are preferred for design flexibility.

Part Context

The LT1509 series belongs to Analog Devices' portfolio of power management integrated circuits. This specific model combines two critical functions in power electronics into one chip. It serves as a compact alternative to using separate controllers for PFC and PWM stages. The ISW variant denotes the industrial temperature grade and SOIC package type.
