LTC3878EGN#PBF

DC DC Switching Controllers Overview

The LTC3878EGN#PBF is a fast, wide operating range, no RSENSE buck DC/DC controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4 V to 38 V and supports output voltages from 800 mV to 34.2 V. The device delivers up to 25 A of output current with a switching frequency of 2 MHz. It features a low static current of 18 uA and works within a temperature range of -40°C to +85°C. The component is housed in a 16-lead SSOP package.

DC DC Switching Controllers Feature Summary

• Eliminates the need for external sense resistors through proprietary current mode control architecture
• Supports high-speed switching at 2 MHz for compact passive component sizing
• Provides precise load regulation with minimal quiescent current consumption

DC DC Switching Controllers Applications

• Point-of-load regulation in telecommunications infrastructure
• Voltage conversion for industrial equipment power supplies
• Power distribution networks in computing systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix EG indicates the commercial temperature grade when sourcing. Confirm the PBF designation ensures lead-free compliance with RoHS standards. Cross-reference the manufacturer's latest datasheet revision to ensure pinout compatibility with existing PCB layouts. Validate that the SSOP-16 package dimensions match the intended footprint requirements before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring high efficiency without the power loss associated with current sensing resistors. The 2 MHz frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Ensure the application input voltage remains within the 4 V to 38 V window. Consider thermal management strategies given the potential for 25 A output currents in dense packaging environments.

DC DC Switching Controllers Part Context

This component belongs to the LTC3878 family of synchronous step-down controllers. It shares architectural similarities with other high-performance buck regulators from Analog Devices but distinguishes itself through its resistorless current sensing capability. The EG variant specifically denotes the commercial temperature range extension suitable for general-purpose electronic applications.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include the LTC3878IUFD#PBF for QFN packaging or the LTC3878IGN#PBF for alternative SSOP variations. Verify thermal performance and pin compatibility when transitioning between package types.
