LTC3769IFE#PBF

DC DC Switching Controllers Overview

The LTC3769IFE#PBF is a synchronous boost controller from Analog Devices, designed for high-efficiency power conversion. It operates with an input voltage range of 4.5 V to 60 V and supports output voltages from 2.3 V to 60 V. The device delivers up to 5 A of output current through its synchronous rectification architecture. Key electrical parameters include a low quiescent current of 28 uA and an adjustable switching frequency ranging from 50 kHz to 900 kHz. It is housed in a TSSOP-EP-20 package and functions within a temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Synchronous boost topology for enhanced efficiency
• Low quiescent current operation for standby applications
• Adjustable switching frequency for EMI optimization
• Integrated shutdown control capability

DC DC Switching Controllers Applications

• Industrial power supplies
• Distributed power systems
• Battery-powered equipment

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the TSSOP-EP-20 package type matches your PCB footprint requirements. Ensure the supplier provides valid documentation for the Analog Devices brand. Cross-reference the manufacturer part number against official distributor catalogs to avoid counterfeit components. Check regional availability restrictions as some distributors may limit sales in certain areas.

DC DC Switching Controllers Selection Notes

Select this component when a wide input voltage range up to 60 V is required for boost applications. The 5 A output current capability suits moderate power levels. Consider the 28 uA quiescent current for battery life extension. The adjustable frequency allows flexibility in filter design. Verify thermal performance within the specified operating temperature range.

DC DC Switching Controllers Part Context

This part belongs to the LTC3769 series of synchronous boost controllers. It shares architectural similarities with other Analog Devices PMICs but is distinct in its 60 V input rating and 5 A current capacity. The IFE variant specifies the industrial temperature grade and TSSOP-EP-20 package. It complements evaluation boards like the DC2173A for design verification.
