LTC7804EUD#PBF

DC DC Switching Controllers Overview

The LTC7804EUD#PBF is a synchronous boost DC-DC switching controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4.5V to 40V and supports switching frequencies between 100kHz and 3MHz. The device features a maximum duty cycle of 100% and provides a positive output configuration. It is housed in a 16-QFN (3x3) surface-mount package with exposed pad. The component is rated for operation at junction temperatures ranging from -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Synchronous rectification architecture for high efficiency
• Capable of 100% duty cycle operation for low input-to-output differential applications
• Integrated frequency control allowing synchronization or spread spectrum modulation

DC DC Switching Controllers Applications

• Industrial power supply systems requiring step-up conversion
• Battery-powered equipment needing voltage boosting
• Automotive electronics operating within specified voltage ranges

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF confirms lead-free and RoHS compliance status according to current manufacturer declarations. Confirm the EUD package designation matches the required 16-QFN (3x3) footprint for PCB layout compatibility. Ensure the temperature grade aligns with the intended operational environment limits.

DC DC Switching Controllers Selection Notes

Select this controller when a synchronous boost topology is required with wide input voltage flexibility up to 40V. Consider the 100% duty cycle capability if the application demands minimal voltage drop between source and load. Evaluate the 16-QFN package constraints against available board space and thermal dissipation requirements for the target design.

DC DC Switching Controllers Part Context

This component belongs to the LTC7804 family of low IQ synchronous boost controllers. It shares functional similarities with other members like the LTC7804EMSE but differs in package type, utilizing the QFN form factor instead of MSOP. The series is designed for applications prioritizing efficiency and compact size in power management solutions.
