Overview
The LT1766IGN#PBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 5.5 V to 60 V and provides a fixed 5 V output at 1.2 A. The device integrates a 1.5 A power switch and operates at a fixed 200 kHz frequency. Key electrical parameters include a quiescent current of 25 uA, load regulation of 0.1%, and shutdown capability. It is housed in a 16-lead SSOP package and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Integrates a high-voltage 1.5 A power switch for efficient step-down conversion
- Features low quiescent current operation to minimize standby power consumption
- Includes internal compensation and soft-start circuitry for simplified design
Applications
- Point-of-load regulation in industrial systems
- Power supplies for embedded controllers
- Battery-powered equipment requiring high efficiency
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance before procurement. Confirm the SSOP-16 package availability matches your PCB footprint requirements. Check official distributor channels for current stock status as supply may be limited. Ensure the operating temperature range meets your environmental specifications.
Selection Notes
Select this component when a wide input voltage range up to 60 V is required. It is suitable for designs needing a fixed 5 V output without external feedback resistors. Consider the 200 kHz switching frequency for balancing component size and efficiency. Verify that the 1.2 A output current meets the load requirements of the target application.
Part Context
This part belongs to the LT1766 family of monolithic buck regulators from Analog Devices. It shares functional similarities with other members of the series but differs in package type and specific output configuration. The IGN variant specifically denotes the SSOP-16 package option within the product line.
Replacement Considerations
LT1766EFE-5#PBF: Alternative package version (TSSOP-16) with identical electrical performance.
