LTC1705EGN

Power Supply Controllers, Monitors Overview

The LTC1705EGN is a dual-channel synchronous switching regulator controller designed for Intel Mobile Pentium processors. It operates with a fixed 550kHz switching frequency and accepts an input voltage range of 3.15V to 5.5V. The device provides three outputs, delivering up to 20A output current with adjustable voltages from 900mV to 2V. It features integrated 5-bit VID control and a 150mA LDO. Packaged in a 28-pin SSOP, it functions within a temperature range of -40°C to +85°C.

Power Supply Controllers, Monitors Feature Summary

• Integrates dual synchronous buck controllers with 5-bit VID interface
• Includes dedicated 150mA low-dropout linear regulator
• Supports precise load regulation with shutdown capability

Power Supply Controllers, Monitors Applications

• Complete power supply controller for Intel Mobile Pentium processors
• Dual-output DC-DC conversion systems requiring VID control
• Portable computing platforms needing integrated voltage regulation

Power Supply Controllers, Monitors Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to limited availability status. Confirm package integrity upon receipt as the SSOP-28 form factor requires careful handling. Cross-reference datasheet revisions to ensure compatibility with specific processor VID requirements before integration into final designs.

Power Supply Controllers, Monitors Selection Notes

Select this controller when designing for legacy Intel Mobile Pentium architectures requiring synchronized dual-phase power delivery. Ensure input voltage sources remain within the specified 3.15V to 5.5V window. Verify that thermal management solutions accommodate the SSOP-28 package constraints while maintaining operation across the full industrial temperature range.

Power Supply Controllers, Monitors Part Context

Part of the LTC1705 series focusing on mobile processor power management. It complements other PMIC components by providing specialized control logic rather than standalone regulation. The EG suffix denotes the commercial grade temperature range and SSOP packaging variant within the broader product family.

Power Supply Controllers, Monitors Replacement Considerations

LTC1705EGN#PBF offers identical electrical specifications but utilizes tube packaging instead of tape and reel.
