LTC3806EDE#PBF

DC DC Switching Controllers Overview

The LTC3806EDE#PBF is a synchronous flyback DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 10 V to 75 V and provides a single output up to 6.9 V at 20 mA. The device features a fixed switching frequency of 250 kHz and a typical quiescent current of 1 mA. It is housed in a 12-lead DFN package and supports operation temperatures from -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Synchronous flyback topology for efficient power conversion
• Integrated shutdown capability for power management
• Optimized load regulation performance

DC DC Switching Controllers Applications

• Isolated power supply designs
• Flyback converter circuits
• Industrial control systems requiring isolation

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS standards before procurement. Confirm the DFN-12 package dimensions match the target PCB footprint. Ensure the supplier source is authorized to guarantee component authenticity and traceability.

DC DC Switching Controllers Selection Notes

Select this controller when an isolated flyback architecture is required with an input voltage exceeding 10 V. The 250 kHz frequency balances size and efficiency for moderate power levels. Verify that the 20 mA output current meets the application requirements, as higher currents may necessitate different topologies or components.

DC DC Switching Controllers Part Context

This component belongs to the LTC3806 series of switching regulators. It is designed for applications requiring galvanic isolation via a flyback transformer. The part integrates the necessary control logic for synchronous rectification, simplifying the design of isolated power stages compared to non-synchronous alternatives.

DC DC Switching Controllers Replacement Considerations

Direct replacement options are not explicitly confirmed in the provided documentation. Evaluate pin-compatible controllers from the same manufacturer family if available. Ensure any substitute maintains the 10 V to 75 V input range and synchronous flyback functionality.
