LTC1628IG#PBF

DC DC Switching Controllers Overview

The LTC1628IG#PBF is a dual synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates within an input voltage range of 3.5 V to 36 V and supports output currents up to 5 A per phase. The device features a programmable switching frequency between 150 kHz and 300 kHz, with a typical quiescent current of 350 µA. Packaged in a 28-lead SSOP, it provides two independent outputs with control features including enable, soft start, and power good indication.

DC DC Switching Controllers Feature Summary

• Dual-channel architecture providing independent synchronous buck regulation for two separate output rails
• Integrated control features including programmable frequency, soft start, and power good status signaling
• Wide input voltage capability supporting standard industrial and commercial bus voltages

DC DC Switching Controllers Applications

• Point-of-load regulation in telecommunications infrastructure equipment
• Voltage conversion for embedded computing systems requiring multiple supply rails
• Industrial control systems utilizing high-efficiency DC-DC conversion

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 PCB footprint dimensions for the 28-SSOP configuration. Confirm that the selected variant meets all environmental compliance standards required for your specific deployment region.

DC DC Switching Controllers Selection Notes

Select this component when dual isolated or non-isolated buck outputs are required from a single controller. Consider the 3.5 V minimum input voltage constraint against your system's lowest operating condition. Evaluate thermal management requirements based on the total output current capacity and ambient operating temperature limits defined in the datasheet.

DC DC Switching Controllers Part Context

This part belongs to the LTC1628 family of high-efficiency dual synchronous buck controllers. It is designed to replace older discrete solutions or single-channel regulators where space and efficiency are critical. The device integrates gate drivers and control logic to minimize external component count while maintaining precise regulation across varying load conditions.

DC DC Switching Controllers Replacement Considerations

Direct pin-compatible alternatives include the LTC1628CG#PBF and LTC1628IUH#PBF, which share the same core functionality but differ in package style and temperature rating. Verify electrical specifications match before substitution.
