LTC3787EGN#PBF

DC DC Switching Controllers Overview

The LTC3787EGN#PBF is a synchronous boost controller from Analog Devices, housed in a 28-lead SSOP package. It operates with an input voltage range of 2.5 V to 38 V and supports output voltages from 1.2 V to 60 V. The device features a programmable switching frequency between 105 kHz and 760 kHz and draws a typical quiescent current of 125 µA. It includes integrated soft-start, current limit, and power-good monitoring functions, operating reliably within a temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Supports dual-output or two-phase synchronous boost configurations for high-current applications
• Integrates PMBus interface for digital control and monitoring capabilities
• Features low quiescent current operation to enhance efficiency during light-load conditions

DC DC Switching Controllers Applications

• Telecommunications infrastructure power supplies
• Battery-powered equipment needing extended runtime through efficient voltage stepping

DC DC Switching Controllers Procurement Notes

Verify the specific suffix EG against the official datasheet to confirm package type and temperature grade. Confirm RoHS compliance status as indicated in the documentation. Check for any recent Product Change Notifications that may affect pinout or electrical characteristics before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component when a synchronous boost topology with digital management is required. Ensure the input voltage does not exceed 38 V and the output requirement stays within 60 V. Verify that the thermal performance of the SSOP-28 package meets the application's heat dissipation needs under maximum load conditions.

DC DC Switching Controllers Part Context

This part belongs to the PolyPhase series of controllers designed for high-efficiency power conversion. It complements other Linear Technology regulators by offering precise current-mode control and synchronization options. The family focuses on reducing external component count while maintaining robust protection features for demanding environments.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include the LTC3787IUFD#PBF for QFN packaging or the LTC3788IGN-1#PBF for similar dual-output boost control. Verify pin compatibility and electrical specifications before swapping.
