LTC3787HGN#PBF

DC DC Switching Controllers Overview

The LTC3787HGN#PBF is a synchronous boost DC/DC controller from the PolyPhase series, manufactured by Analog Devices Inc. It operates within an input voltage range of 4.5V to 38V and supports adjustable switching frequencies between 105kHz and 760kHz. The device features a maximum duty cycle of 96% and includes integrated current limit, enable, frequency control, power good, and soft start functions. Packaged in a 28-pin SSOP tube, it is designed for high-efficiency step-up applications with a junction temperature range of -40°C to +125°C.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when ordering. Confirm availability status as distribution channels may report limited stock or discontinuation notices. Ensure the SSOP-28 package matches your PCB footprint requirements. Cross-reference the datasheet revision date to confirm feature compatibility before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring a single-output boost topology with synchronous rectification. The wide input voltage range suits battery-fed systems. Consider the 28-pin SSOP package constraints for thermal management. Verify that the required output voltage falls within the controller's operational limits defined in the electrical characteristics table.

DC DC Switching Controllers Part Context

This part belongs to the PolyPhase series of power management ICs from Analog Devices. It serves as a standalone controller for external MOSFETs in boost configurations. The HGN variant specifically denotes the SSOP-28 package option, distinguishing it from QFN or other package types within the same functional family.

DC DC Switching Controllers Replacement Considerations

Check for direct pin-compatible alternatives within the Analog Devices portfolio. Verify if the LTC3787HGN#TRPBF (tape and reel) meets packaging needs instead of the tube version. Ensure any substitute maintains the 4.5V to 38V input range and synchronous operation.
