LTC3823IUH#PBF

DC DC Switching Controllers Overview

The LTC3823IUH#PBF is a synchronous step-down DC/DC controller from Analog Devices, designed for high-efficiency power conversion. It operates with an input voltage range of 4.5 V to 36 V and supports output voltages from 600 mV to 27 V. The device delivers up to 25 A of output current and features a programmable switching frequency between 100 kHz and 1 MHz. Packaged in a 32-lead QFN (5x5 mm) with exposed pad, it functions within a temperature range of -40°C to +125°C TJ.

DC DC Switching Controllers Feature Summary

• Integrates dual N-channel power MOSFET drivers for synchronous rectification without requiring external sense resistors.
• Supports digital control via I2C and PMBus interfaces for precise regulation and monitoring.
• Includes comprehensive protection features such as over-current, over-voltage, and thermal shutdown.

DC DC Switching Controllers Applications

• Point-of-load (POL) converters in telecommunications infrastructure
• High-density server and workstation power distribution systems
• Industrial equipment requiring robust step-down regulation

DC DC Switching Controllers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with required I2C/PMBus protocols during integration. Confirm availability status through authorized distributors as supply conditions may vary.

DC DC Switching Controllers Selection Notes

Select this component when a single-phase synchronous buck solution with digital interface capabilities is required. It is suitable for applications needing high current density and precise voltage regulation. Compare against multi-phase alternatives if higher current or reduced ripple is necessary.

DC DC Switching Controllers Part Context

This part belongs to the LTC3823 family of fast, no-resistor-sense synchronous controllers. It differs from other models by its specific pinout and integrated driver strength optimized for the 32-lead QFN package. It serves as a compact alternative to discrete solutions in space-constrained designs.

DC DC Switching Controllers Replacement Considerations

Direct replacements include LTC3823EUH#PBF for extended temperature ranges or LTC3823IGN#PBF for different packaging options. Verify pin compatibility and electrical specifications before substitution.
