LT1576CS8-SYNC#PBF

Overview

The LT1576CS8-SYNC#PBF is a monolithic buck mode switching regulator manufactured by Analog Devices Inc. It integrates a 1.5A switch, oscillator, and control circuitry into an 8-SOIC package. The device operates at a fixed frequency of 200kHz and features a SYNC pin for external clock synchronization. It supports a wide input voltage range and provides positive adjustable output voltage regulation with high efficiency.

Feature Summary

Integrates a 1.5A power switch and complete control circuitry for step-down conversion
Features a dedicated SYNC pin for direct logic-compatible external oscillator synchronization
Provides positive adjustable output voltage regulation with high line and load regulation

Applications

Battery-powered systems requiring efficient step-down conversion
Industrial control systems utilizing distributed power architectures
Portable equipment needing regulated lower voltages from higher supply rails

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence when ordering. Confirm the SYNC variant designation matches system synchronization requirements. Ensure the 8-SOIC package dimensions align with PCB layout constraints. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid counterfeit components.

Selection Notes

Select this component when a fixed 200kHz switching frequency is required alongside external synchronization capabilities. The integrated 1.5A switch suits moderate current loads without external pass transistors. Consider the wide input voltage tolerance for applications with varying supply conditions. Evaluate thermal performance within the SOIC package for the expected duty cycle and ambient temperature.

Part Context

This part belongs to the LT1576 family of monolithic switching regulators designed for high-efficiency DC-DC conversion. The CS8 suffix denotes the commercial temperature range and 8-pin SOIC plastic package. The SYNC variant specifically includes functionality for phase alignment in multi-regulator systems or noise reduction through jitter spreading.
