DC DC Switching Controllers datasheet and documents for LTC3805EDD-5#PBF

LTC3805EDD-5#PBF

DC DC Switching Controllers Overview

The LTC3805EDD-5#PBF is a current mode DC/DC controller designed for flyback, boost, and SEPIC converter applications. It drives an N-channel MOSFET with an adjustable switching frequency ranging from 70 kHz to 700 kHz. The device supports output voltages between 800 mV and 75 V with a maximum output current of 2 A. Quiescent current is 360 μA during normal operation and 40 μA in micropower startup. It operates within a temperature range of -40°C to +125°C and is housed in a 10-lead DFN EP package.

DC DC Switching Controllers Feature Summary

Adjustable frequency current mode control for flexible converter design
Programmable soft-start with automatic restart capability
Integrated overcurrent sensing for overload protection
Micropower startup mode reduces quiescent current consumption

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'EDD' against official Analog Devices documentation to confirm the exact package type (DFN EP) and industrial temperature grade (-40°C to +125°C). Ensure the '-5' designation aligns with the required voltage accuracy specifications. Cross-reference the datasheet revision history for any recent manufacturing changes or pinout updates before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component when designing isolated or non-isolated converters requiring precise current mode control. The adjustable frequency allows optimization for efficiency and component size. Verify that the external resistor network correctly sets the desired switching frequency and slope compensation. Ensure the input voltage range supports the internal shunt regulator or direct low-impedance supply requirements specified in the electrical characteristics.
