LT1956EGN#TRPBF

Overview

The LT1956EGN#TRPBF is a high-voltage, monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range from 5.5V to 60V and provides a fixed 5V output. The device integrates a 1.2A power switch and functions at a fixed 500kHz switching frequency. Packaged in a 16-lead SSOP, it supports operation temperatures from -40°C to +125°C.

Feature Summary

• Integrates a high-efficiency 1.2A power switch for compact design
• Fixed 500kHz switching frequency reduces external component size
• Current mode architecture ensures fast transient response and loop stability

Applications

• Industrial point-of-load regulation
• Automotive subsystem power distribution
• High-voltage battery-powered equipment

Procurement Notes

Verify the specific suffix #TRPBF against official Analog Devices documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the SSOP-16 package variant matches the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5V output is required from a high-voltage bus up to 60V. The integrated 1.2A switch capability suits moderate current loads without requiring external passives. Verify that the 500kHz frequency aligns with EMI constraints and thermal management capabilities of the enclosure.

Part Context

This part belongs to the LT1956 family of high-voltage buck regulators. It shares architectural similarities with other members like the LT1956EFE-5 but differs in package type (SSOP vs TSSOP) and specific current ratings. It serves as a solution for space-constrained applications needing robust high-voltage input handling.

Replacement Considerations

LT1956EGN-5#TRPBF is a documented alternative within the same series offering identical electrical characteristics and pinout compatibility.
