LTC3826IG-1#TRPBF

DC DC Switching Controllers Overview

The LTC3826IG-1#TRPBF is a dual-channel synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4 V to 36 V and supports output voltages from 800 mV to 10 V. The device delivers up to 25 A per channel and features a fixed switching frequency of 390 kHz. It utilizes an SSOP-28 package and functions within a temperature range of -40 °C to +85 °C, maintaining a quiescent current of 30 µA.

DC DC Switching Controllers Feature Summary

• Dual independent channels for simultaneous multi-rail power distribution
• Synchronous rectification driving all N-channel MOSFET stages
• Integrated soft-start and tracking capabilities for controlled ramp-up

DC DC Switching Controllers Applications

• Multi-voltage server and telecom backplane regulation
• Point-of-load conversion for high-density computing systems
• Industrial equipment requiring isolated or synchronized power rails

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF against official Analog Devices documentation to confirm tape-and-reel packaging and industrial temperature grade specifications. Ensure compatibility with existing board layouts for the SSOP-28 footprint before procurement. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency and thermal performance characteristics.

DC DC Switching Controllers Selection Notes

Select this component when designing systems requiring two independent regulated outputs from a single intermediate bus voltage. The fixed 390 kHz frequency allows for optimized inductor sizing while balancing efficiency and transient response. Consider the 30 µA quiescent current for applications prioritizing standby power conservation in active regulation modes.

DC DC Switching Controllers Part Context
