LTC3814EFE-5#PBF

DC DC Switching Controllers Overview

The LTC3814EFE-5#PBF is a synchronous step-up switching regulator controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4.5 V to 55 V and supports output voltages from 4.5 V to 60 V. The device utilizes current mode control architecture and features a fixed 1 MHz switching frequency. It is housed in a TSSOP-16 package and functions within a temperature range of -40°C to +125°C. The controller draws a quiescent current of 224 µA and requires a 3 mA operating supply current.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the TSSOP-16 package type matches your PCB footprint requirements. Ensure the 4.5 V to 55 V input range aligns with your system's supply rails. Check for any obsolescence notices or limited availability status directly from Analog Devices before finalizing procurement plans.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring high-voltage boost conversion up to 60 V. The fixed 1 MHz frequency allows for compact passive component selection. Verify that the external MOSFETs can handle the required current levels, as this is a controller without integrated switches. Consider thermal performance in the TSSOP-16 package for your specific load conditions.
