Overview
The LT1766EGN-5#PBF is a monolithic buck switching voltage regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 5.5 V to 60 V and provides a fixed output voltage of 5 V. The device delivers an output current of 1.2 A at a fixed switching frequency of 200 kHz. It features a low quiescent current of 25 uA and includes a shutdown function for power management. The component is housed in a 16-pin SSOP package and supports surface mount installation. It functions within a temperature range of 0°C to +125°C.
Feature Summary
- Integrated high-voltage monolithic buck converter topology
- Fixed 5 V output configuration with 1.2 A current capability
- Low static current consumption for efficiency optimization
- Dedicated shutdown pin for system power control
Applications
- Industrial point-of-load regulation
- Battery-powered systems requiring step-down conversion
- General-purpose DC/DC power supply designs
Procurement Notes
Verify availability status as the part may be subject to limited supply or factory special orders. Confirm RoHS compliance details through official documentation. Ensure the SSOP-16 package variant matches design requirements. Check for any product change notifications affecting specifications or packaging before finalizing procurement plans.
Selection Notes
Select this component when a fixed 5 V output is required from a wide input voltage range up to 60 V. The 200 kHz switching frequency allows for compact passive component selection. Consider the thermal performance in the SSOP-16 package for the intended load current. Verify that the 1.2 A output current meets the application demands without exceeding thermal limits.
Part Context
This part belongs to the LT1766 series of high-voltage buck regulators. It shares functional similarities with other variants in the family but differs in package type and specific output voltage settings. The EG suffix indicates the SSOP-16 package, distinguishing it from the EFE TSSOP-16 variant. It serves as a solution for efficient power conversion in space-constrained applications.
Replacement Considerations
LT1766EFE-5#PBF offers identical electrical specifications but utilizes a TSSOP-16 package instead of SSOP-16. Verify pinout compatibility and physical footprint differences before substitution.
