LTC1148CS-5#TRPBF

DC DC Switching Controllers Overview

The LTC1148CS-5#TRPBF is a high-efficiency synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates within an input voltage range of 3.5 V to 20 V and delivers a fixed 5 V output at up to 700 mA. The device features a 250 kHz switching frequency, 160 µA quiescent current, and includes shutdown functionality. Packaged in a 14-pin SOIC for surface mount installation, it supports operation from 0°C to +70°C.

DC DC Switching Controllers Feature Summary

Synchronous buck topology for enhanced efficiency
Integrated power switch for compact design
Fixed 5 V output regulation capability
Shutdown pin for power management control

DC DC Switching Controllers Applications

Portable battery-powered equipment
Industrial control systems
Embedded computing modules

DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches exactly to avoid confusion with non-reel variants like PBF. Check RoHS compliance status as required by project specifications before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring a fixed 5 V rail from higher input voltages. The 700 mA output current suits moderate load requirements. Consider the 250 kHz frequency for balancing size and noise. Verify thermal performance in the target enclosure given the SOIC package constraints.

DC DC Switching Controllers Part Context

This part belongs to the LTC1148 series of synchronous step-down regulators. It shares functional similarities with other parts in the family but is distinguished by its fixed 5 V output and specific packaging. The CS5 designation typically refers to the commercial temperature grade and package type within the broader product line.
