LT1766EGN#PBF

Overview

The LT1766EGN#PBF is a monolithic buck switching regulator manufactured by Analog Devices Inc., housed in a 16-lead SSOP package. It operates with an input voltage range of 5.5V to 60V and delivers up to 1.2A output current at a fixed 5V output. The device features a 200kHz switching frequency, 25µA quiescent current, and supports shutdown functionality. It functions within a temperature range of 0°C to +125°C junction temperature.

Feature Summary

• Integrated synchronous rectification for high efficiency
• Fixed 5V output configuration with overcurrent protection
• Shutdown pin for low power standby modes

Applications

• Point-of-load regulation in industrial systems
• Battery-powered equipment requiring efficient step-down conversion
• General-purpose DC/DC power supply designs

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence when sourcing. Confirm the SSOP-16 package dimensions match your PCB footprint requirements. Ensure the operating junction temperature rating aligns with your thermal management strategy for sustained 1.2A loads.

Selection Notes

Select this component for applications requiring a wide input voltage range up to 60V with a fixed 5V output. It is suitable where moderate current capacity of 1.2A is sufficient. Consider the 200kHz frequency for balancing component size and efficiency against noise sensitivity.

Part Context

This part belongs to the LT1766 series of monolithic buck regulators from Analog Devices. It shares architectural similarities with other devices in the family but is distinct due to its specific 5V fixed output and 1.2A current rating. The EG suffix denotes the commercial temperature grade and SSOP packaging.

Replacement Considerations

LT1766EGN-5#PBF is a confirmed equivalent part number representing the same functional specifications and package type.
