LTC1628IG-SYNC#PBF

DC DC Switching Controllers Overview

The LTC1628IG-SYNC#PBF is a high-performance dual step-down switching regulator controller from Analog Devices, designed to drive all N-channel synchronous power MOSFET stages. It features a constant frequency current mode architecture with a switchable frequency range of 150 kHz to 300 kHz and phase-lock capability. The device supports an input voltage range of 3.5 V to 36 V and operates within a temperature range of -40°C to +85°C. Packaged in a 28-lead SSOP, it provides two independent output channels for efficient power management.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'SYNC' indicates phase-lock compatibility when integrating into multi-controller designs. Confirm package integrity for the 28-SSOP form factor during inspection. Ensure input voltage specifications align with system requirements before deployment. Cross-reference datasheet revisions for any pinout or electrical characteristic updates prior to finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component when dual isolated outputs or synchronized multi-phase operation are required. The SYNC variant enables clock synchronization with other controllers in complex power trees. Evaluate thermal performance based on the SSOP package limitations compared to QFN alternatives. Verify that the external MOSFET selection matches the controller's drive capabilities for optimal efficiency.
