LTC7802EUFDM-3.3#PBF

DC DC Switching Controllers Overview

The LTC7802EUFDM-3.3#PBF is a dual-phase synchronous step-down controller from Analog Devices, designed for high-efficiency power conversion with a 40V input range and 3MHz switching frequency. It features low quiescent current and integrated spread spectrum modulation to reduce EMI. The device includes an internal 3.3V LDO regulator for bias supply, eliminating the need for external auxiliary power in many applications. It supports clock synchronization and offers comprehensive protection features including overvoltage, overcurrent, and thermal shutdown.

DC DC Switching Controllers Feature Summary

• Dual-phase synchronous buck control architecture
• Integrated 3.3V bias regulator
• Spread spectrum modulation for EMI reduction
• Clock synchronization capability

DC DC Switching Controllers Applications

• Industrial point-of-load regulation
• Telecommunications infrastructure power supplies
• Automotive electronics systems
• Computing and networking equipment

DC DC Switching Controllers Procurement Notes

Verify the specific suffix '3.3' indicates the integrated bias voltage configuration. Confirm package type EUFDM matches design requirements. Check RoHS compliance status as indicated by '#PBF'. Ensure availability through authorized distributors given potential supply chain variations.

DC DC Switching Controllers Selection Notes

Select this component when dual-phase output is required within a 40V input window. The integrated 3.3V LDO simplifies board design by removing external bias components. Consider the 3MHz frequency for smaller passive sizes compared to lower-frequency alternatives. Verify thermal performance requirements for the QFN package.

DC DC Switching Controllers Part Context

Part of the LTC7802 family of high-performance synchronous step-down controllers. Designed for applications requiring high efficiency and low noise. Shares core control logic with other variants in the series but differs in bias supply integration and pinout configurations.

DC DC Switching Controllers Replacement Considerations

LTC7802EUFDM (without 3.3 suffix) requires external bias supply. LTC7801EUFD is single-phase. LTC7805RUFDM is dual-phase but different feature set. Verify pin compatibility before substitution.
