LTC1874EGN#PBF

DC DC Switching Controllers Overview

The LTC1874EGN#PBF is a dual synchronous current-mode step-down DC/DC controller manufactured by Analog Devices Inc. It operates with two independent constant-frequency channels within a 2.5V to 9.8V input voltage range, delivering up to 20A output current per channel. The device features an adjustable switching frequency of 550kHz and supports adjustable output voltages. Designed for surface-mount installation in an SSOP-16 package, it functions reliably across an operating temperature range of -40°C to +85°C while maintaining a low quiescent current of 270µA.

DC DC Switching Controllers Feature Summary

• Dual-channel architecture providing independent control over two separate buck converter outputs
• Current-mode control topology ensuring stable operation and simplified compensation design
• Integrated shutdown capability for power management and system standby modes

DC DC Switching Controllers Applications

• Multi-rail power distribution systems requiring simultaneous voltage regulation
• Industrial equipment power supplies needing high-current step-down conversion
• Telecommunications infrastructure utilizing dense board layouts

DC DC Switching Controllers Procurement Notes

Verify the specific suffix and package variant against official Analog Devices documentation before procurement. Confirm that the SSOP-16 footprint matches your PCB layout requirements. Ensure environmental compliance standards align with project specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components. Validate thermal performance expectations based on actual load conditions.

DC DC Switching Controllers Selection Notes

Select this component when designing systems requiring two isolated or non-isolated regulated rails from a single input source. The dual-channel design reduces component count compared to using separate single-channel controllers. Consider the 550kHz switching frequency for balancing efficiency and passive component size. Evaluate the 20A current capability against peak load demands to ensure adequate thermal headroom in the SSOP-16 package.
