LT1776CS8#PBF

Overview

The LT1776CS8#PBF is a high-efficiency buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 7V to 40V and provides an adjustable output voltage up to 30V. The device delivers a maximum switch current of 550mA at a fixed switching frequency of 100kHz. Packaged in an 8-SOIC surface-mount case, it supports positive output configuration with a minimum output voltage of 1.24V. The component functions within a junction temperature range of 0°C to 125°C and lacks synchronous rectification.

Feature Summary

• High efficiency step-down regulation topology
• Wide input voltage capability for diverse power sources
• Integrated shutdown control for power management

Applications

• Automotive DC/DC conversion systems
• Telecommunications 48V step-down applications
• IEEE1394 step-down converter designs

Procurement Notes

Verify the specific suffix CS8 corresponds to the 8-pin SOIC package variant rather than other pin counts. Confirm RoHS3 compliance status through official material declarations. Ensure the ordering part number matches the exact thermal and electrical specifications required for the target design environment.

Selection Notes

Select this component when a non-synchronous buck regulator is required for moderate current loads up to 550mA. Consider the 100kHz switching frequency for standard passive component sizing. Evaluate the 7V to 40V input range against available supply rails to ensure adequate headroom for the desired output voltage.

Part Context

This part belongs to the LT1776 series of wide input range, high-efficiency buck switching regulators from Analog Devices. It shares functional similarities with the LT1676 but differs in packaging and specific electrical characteristics. The CS8 designation indicates a commercial grade temperature range and an 8-lead small outline integrated circuit package.
