LTC1709EG-7#TRPBF

DC DC Switching Controllers Overview

The LTC1709EG-7#TRPBF is a high-efficiency synchronous step-down DC/DC controller designed for industrial applications. It features a two-phase architecture with five-bit VID input capability and current mode control. The device operates within a switching frequency range of 140kHz to 310kHz and supports a maximum duty cycle of 0.995. It accepts a supply voltage between 4V and 36V, delivering positive output configurations through two output stages. Packaged in a 36-SSOP housing, it functions reliably across an operating temperature range of -40°C to 85°C.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging and RoHS compliance. Confirm the EG variant matches the required thermal and mechanical specifications for the target PCB layout. Ensure the 36-SSOP footprint aligns with assembly capabilities. Cross-reference the datasheet revision to validate feature sets against current production standards before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component when a dual-phase synchronous buck solution with VID programmability is required. It suits designs needing high efficiency and precise voltage regulation in industrial environments. Consider the 36-pin package size for board space constraints. Verify that the input voltage range of 4V to 36V covers the system's operational requirements.

DC DC Switching Controllers Part Context

This part belongs to the LTC1709 family of high-performance synchronous step-down controllers. The EG-7 variant specifically denotes the 36-SSOP package and commercial/industrial temperature rating. It is manufactured by Analog Devices Inc., continuing the legacy of Linear Technology power management solutions. The TRPBF suffix confirms the reel packaging format and lead-free construction.

DC DC Switching Controllers Replacement Considerations

The LTC1709EG-85#TRPBF is a confirmed substitute within the same family, sharing identical pinout and functionality but potentially differing in specific electrical characteristics or documentation revisions. Verify compatibility with existing design parameters before swapping.
