LT1576CS8#TRPBF

Overview

The LT1576CS8#TRPBF is a monolithic buck mode switching regulator manufactured by Analog Devices Inc. It integrates a 1.5A power switch, oscillator, and control circuitry into an 8-SOIC package. The device operates at a fixed switching frequency of 200kHz. It supports an input voltage range up to 25V. The output voltage is adjustable from 1.21V to the input rail. The component is rated for operation within a temperature range of 0°C to +125°C.

Feature Summary

Integrates a high-current 1.5A power switch on the die
Operates at a fixed 200kHz switching frequency
Provides adjustable positive output voltage regulation
Designed for compact surface-mount applications

Applications

Point-of-load DC-DC conversion
Battery-powered equipment power supplies
General-purpose step-down voltage regulation

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when reviewing distributor listings. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches the exact SOIC-8 configuration. Cross-reference the datasheet revision date to ensure compatibility with current design requirements. Validate RoHS compliance status through official documentation.

Selection Notes

Select this component for designs requiring a compact solution with integrated power switching capabilities. The 200kHz frequency allows for smaller external inductors and capacitors compared to lower-frequency alternatives. Consider the thermal performance of the SOIC-8 package under maximum load conditions. Verify that the input voltage does not exceed the 25V absolute maximum rating.

Part Context

This part belongs to the LT1576 family of switching regulators. It shares the core architecture with variants such as the LT1576CS8-SYNC#TRPBF, which offers synchronization features. The CS8 designation identifies the commercial temperature grade and SOIC-8 package style used across this product line.
