LTC3850IGN#PBF

DC DC Switching Controllers Overview

The LTC3850IGN#PBF is a dual-channel, two-phase synchronous step-down switching controller manufactured by Analog Devices Inc. It operates within a 4V to 30V input voltage range and supports output voltages from 0.8V to 23.32V. The device features a programmable switching frequency between 700kHz and 860kHz, with a typical operating point at 780kHz. It provides two independent outputs in a 28-pin SSOP package, designed for high-efficiency power conversion with current-mode control architecture.

DC DC Switching Controllers Feature Summary

Dual-channel architecture with 180-degree phase shift to minimize input capacitance and supply noise
OPTI-LOOP compensation for optimized transient response across wide output capacitance and ESR ranges
Synchronous clock capability allowing synchronization to an external master clock
Integrated soft-start and tracking functionality via independent TK/SS pins

DC DC Switching Controllers Applications

Laptop and notebook computer power systems
Portable instrumentation power supplies
Battery-powered digital equipment
DC power distribution systems

DC DC Switching Controllers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required pinout and thermal characteristics. Check RoHS compliance status against regional regulations. Ensure storage conditions meet moisture sensitivity level requirements prior to soldering. Validate that the package type aligns with PCB footprint specifications.

DC DC Switching Controllers Selection Notes

Select this controller when designing dual-rail DC-DC converters requiring precise phase alignment. Consider the 28-SSOP package constraints for thermal management and board space. Evaluate the 700kHz to 860kHz frequency range against inductor size and efficiency targets. Verify compatibility with N-channel MOSFET gate drive requirements. Assess input voltage stability within the 4V to 30V operational window.

DC DC Switching Controllers Part Context

The LTC3850 belongs to Analog Devices' PolyPhase family of high-performance switching controllers. It complements other models like the LTC3855 and LTC3857 by offering dual-channel control with fixed frequency operation. The IGN variant specifically denotes the industrial temperature grade and SSOP packaging option within the broader LTC3850 product line.
