LTC7802EUFDM#PBF

DC DC Switching Controllers Overview

The LTC7802EUFDM#PBF is a dual, two-phase synchronous step-down controller from Analog Devices Inc., designed for high-efficiency power conversion. It operates with an input voltage range up to 40V and supports switching frequencies of 3MHz. The device features low quiescent current (IQ) capabilities and incorporates spread spectrum technology to reduce electromagnetic interference (EMI). It provides precise output regulation through integrated feedback loops and includes comprehensive protection mechanisms such as overcurrent and thermal shutdown. The component is housed in a compact QFN package suitable for space-constrained applications requiring robust DC/DC conversion performance.

DC DC Switching Controllers Feature Summary

• Dual-phase architecture enables interleaved operation for reduced input ripple and improved transient response
• Integrated spread spectrum modulation minimizes conducted EMI without external filtering requirements
• Low IQ design optimizes efficiency across varying load conditions and standby states

DC DC Switching Controllers Applications

• Industrial automation control systems
• Telecommunications infrastructure power supplies
• Automotive electronics and infotainment modules

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'EUFDM#PBF' against official Analog Devices documentation to confirm pinout compatibility and RoHS status. Ensure that the ordering information matches the exact temperature grade and package variant required for your design. Cross-reference the datasheet revision date to confirm any updates to electrical characteristics or recommended operating conditions before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this controller when dual-channel synchronous rectification is required within a 40V input limit. Consider the 3MHz switching frequency for smaller passive component sizes compared to lower-frequency alternatives. Evaluate the low IQ feature if system standby power consumption is a critical constraint. Confirm that the QFN-28 package fits within the PCB footprint constraints and thermal management strategy of the target application.

DC DC Switching Controllers Part Context

The LTC7802 belongs to Analog Devices' family of high-performance synchronous buck controllers. It complements other devices like the LTC7805 by offering dual-phase capability rather than single-phase high-current solutions. This part is distinct from battery chargers like the LTC4162 or surge stoppers like the LTC7862, focusing specifically on efficient DC/DC voltage stepping for general-purpose power rails.
