Overview
The LT1766IFE#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 an adjustable output voltage. The device supports an output current of 1.2 A and features a fixed switching frequency of 200 kHz. It includes a shutdown function and has a quiescent current of 25 uA. The component is housed in a TSSOP-16 package with exposed pad, suitable for surface mount installation, and operates within a temperature range of -40°C to +125°C.
Feature Summary
- Integrates a high-voltage power switch capable of handling input voltages up to 60 V.
- Features a fixed 200 kHz switching frequency to optimize external component size.
- Includes a shutdown pin to minimize standby power consumption.
Applications
- Industrial point-of-load regulation
- Battery-powered systems requiring high input voltage tolerance
- Distributed power architectures
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm availability status as distribution channels may list limited stock or end-of-life notifications. Ensure the TSSOP-16 package variant matches your PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component for applications requiring wide input voltage ranges and moderate output currents. The fixed 200 kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider thermal performance due to the exposed pad design for effective heat dissipation in dense layouts.
Part Context
This part belongs to the LT1766 family of high-voltage step-down regulators. It shares functional similarities with other members like the LT1766EFE-5#PBF but differs in output configuration and package type. The IFE suffix denotes the TSSOP-16 package with industrial temperature rating.
Replacement Considerations
LT1766EFE-5#PBF offers a fixed 5 V output in a similar package. LT1766HFE#TR provides adjustable output in a tape-and-reel format. Verify pin compatibility and thermal characteristics when substituting.
