LT1375CS8#PBF

Overview

The LT1375CS8#PBF is a monolithic buck mode switching regulator manufactured by Analog Devices Inc. It integrates a 1.5A power switch, oscillator, and control logic on a single die. The device operates at a fixed switching frequency of 500kHz, enabling the use of compact external components. It accepts an input voltage range from 6V to 25V and provides a regulated 5V output with a maximum current capacity of 1.25A. The component is housed in an 8-pin SOIC package.

Feature Summary

• Integrates a high-current 1.5A internal switch for efficient power handling
• Fixed 500kHz switching frequency reduces external passive component size
• Monolithic design includes all necessary oscillator and control circuitry

Applications

• Point-of-load DC-DC conversion
• General purpose step-down voltage regulation
• Battery-powered systems requiring efficient voltage reduction

Procurement Notes

Verify the specific suffix and manufacturer details against official Analog Devices documentation to ensure compatibility. Confirm that the operating temperature range and package type meet your system requirements. Check for any recent product change notices or end-of-life announcements directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a fixed 5V output is required from an input voltage between 6V and 25V. The integrated 1.5A switch supports loads up to 1.25A. The 500kHz frequency is suitable for designs prioritizing smaller inductor and capacitor sizes over ultra-low noise applications. Ensure the thermal management strategy accommodates the SOIC-8 package constraints.

Part Context

This part belongs to the LT1375 series of switching regulators. It is specifically configured for a fixed 5V output. Other variants in the series may offer different output voltages or pinouts. The CS8 designation indicates the commercial temperature range and SOIC-8 package style.

Replacement Considerations

LT1375IN8-5#PBF is a documented parameter-equivalent alternative offering through-hole packaging.
