LT1241CS8#PBF

Overview

The LT1241CS8#PBF is an 8-pin, fixed frequency, current mode pulse width modulator manufactured by Analog Devices Inc. It operates within a supply voltage range of 8.2V to 25V and supports a switching frequency of 500kHz. The device features a maximum duty cycle of 48% and is housed in an 8-SOIC package. As an improved plug-compatible version of industry-standard devices, it provides high-speed current mode control for DC-DC converter applications.

Feature Summary

High-speed current mode pulse width modulation architecture
Fixed frequency operation capability
Improved plug compatibility with industry standard designs

Applications

Isolated flyback converters
Non-isolated buck converters
Forward converters

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance per RoHS standards. Confirm the 8-SOIC package dimensions match the target PCB footprint. Ensure the operating temperature range aligns with system requirements. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm availability status and authenticity before procurement.

Selection Notes

Select this component when a fixed-frequency current mode controller is required for isolated or non-isolated topologies. The 500kHz switching frequency offers a balance between efficiency and component size. Consider the 48% maximum duty cycle limitation for input-to-output voltage ratio calculations. Verify that the 8.2V minimum supply voltage meets the circuit's startup and operating conditions.

Part Context

The LT1241 series consists of 8-pin, fixed frequency, current mode pulse width modulators. These devices are designed as improved plug-compatible versions of earlier industry-standard controllers. The series includes variants such as the LT1241IN8 and LT1241CS8, offering reliable performance for various DC-DC conversion architectures.

Replacement Considerations

The datasheet identifies the LT1241 series as improved plug-compatible versions of industry standard devices. Specific substitute part numbers are not explicitly listed in the provided source material. Engineers should verify pinout and electrical parameter compatibility with legacy components before substitution.
