LT1956EGN#PBF

Overview

The LT1956EGN#PBF is a high-voltage, step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range from 5.5 V to 60 V and delivers up to 1.2 A of output current. The device integrates a 500 kHz fixed-frequency PWM controller and utilizes SSOP-16 surface-mount packaging. Designed for industrial applications, it functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a high-voltage power switch capable of handling up to 60 V input
• Features a fixed 500 kHz switching frequency for optimized passive component size
• Includes internal compensation and soft-start circuitry

Applications

• Industrial point-of-load regulation
• Battery-powered equipment
• Automotive systems

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout compatibility and thermal characteristics. Confirm RoHS compliance status as manufacturing revisions may alter material declarations. Cross-reference the manufacturer's latest datasheet to ensure the part meets current environmental standards before finalizing procurement specifications.

Selection Notes

Select this component when a wide input voltage range exceeding standard regulators is required. The integrated high-voltage switch eliminates external MOSFETs, simplifying the design. Ensure the application demands a fixed 500 kHz frequency and fits within the SSOP-16 package constraints for optimal thermal performance.

Part Context

This part belongs to the LT1956 family of high-voltage buck converters. It shares core architecture with variants offering different output voltages or packages. The EG suffix denotes the SSOP-16 package type, while PBF indicates lead-free construction. This series targets robust power management in harsh environments.

Replacement Considerations

LT1956EGN-5#TRPBF: Identical electrical specifications; differs in tape-and-reel packaging instead of tube.
