Overview
The LT1766IFE#TRPBF is a monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 5.5 V to 60 V and delivers up to 1.2 A output current. The device integrates a power switch and operates at a fixed switching frequency of 200 kHz. It features adjustable output voltage capability, low quiescent current of 2.5 mA, and supports shutdown mode. The component is housed in a 16-lead TSSOP package with exposed pad and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Integrates high-voltage power switch for buck topology
- Supports wide input voltage range up to 60 V
- Includes shutdown control for power management
Applications
- Industrial point-of-load regulation
- Battery-powered systems requiring high input tolerance
- General-purpose DC-DC conversion
Procurement Notes
Verify the exact part number LT1766IFE#TRPBF against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure the procurement source provides valid traceability and authenticity guarantees. Check for RoHS compliance status as indicated in the manufacturer datasheet before finalizing acquisition.
Selection Notes
Select this component when designing circuits requiring a wide input voltage range up to 60 V with moderate output current capabilities. The fixed 200 kHz switching frequency allows for compact external component sizing compared to lower-frequency alternatives. Consider the TSSOP-16 package constraints for thermal management and PCB layout requirements during the design phase.
Part Context
This part belongs to the LT1766 family of high-voltage step-down switching regulators. It shares core architecture with variants like LT1766EFE-5#PBF but differs in packaging and reel configuration. The family is designed for applications needing robust performance across varying input conditions without requiring external bootstrap components.
Replacement Considerations
LT1766EFE-5#PBF is a documented variant within the same product family offering similar electrical characteristics in a tube package.
