Overview
The LT1766IFE-5#PBF is a monolithic buck switching regulator manufactured by Analog Devices Inc., housed in a 16-lead TSSOP package. It operates with an input voltage range of 5.5 V to 60 V and provides a fixed 5 V output at up to 1.2 A continuous current. The device features a 200 kHz switching frequency, low quiescent current of 25 uA, and supports shutdown functionality. It functions within a temperature range of 0°C to +125°C.
Feature Summary
- Integrates a high-voltage power switch for efficient step-down conversion
- Includes internal compensation for simplified external component requirements
- Supports shutdown mode to minimize standby power consumption
Applications
- Industrial control systems requiring isolated or non-isolated power regulation
- Distributed power architectures in telecommunications equipment
- Battery-powered devices needing efficient voltage stepping from higher bus voltages
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm that the EFE variant differs only in package type while maintaining identical electrical characteristics. Ensure compatibility with existing thermal management designs due to the TSSOP form factor.
Selection Notes
Select this component for applications requiring wide input voltage ranges up to 60 V with moderate output currents. Consider the fixed 5 V output constraint; use adjustable variants if different voltage levels are needed. Evaluate thermal dissipation requirements based on the load current and input-output voltage differential.
Part Context
This part belongs to the LT1766 series of high-voltage step-down switching regulators. It complements other Analog Devices power management ICs designed for robust industrial and commercial environments. The series emphasizes ease of use through internal compensation and high integration levels.
Replacement Considerations
LT1766EFE-5#PBF serves as a direct pin-compatible alternative differing primarily in package style.
