LT1959CS8#TRPBF

Overview

The LT1959CS8#TRPBF is a monolithic buck mode switching regulator from Analog Devices, functionally identical to the LT1506 but optimized for lower output voltage applications. It operates as a DC-DC converter with an input voltage range of 4V to 16V and provides a single adjustable output between 1.21V and 2.42V at up to 8.5A. The device features a 500kHz switching frequency and is housed in an 8-pin SOIC package.

Feature Summary

• Monolithic buck mode switching regulator design
• Optimized for low output voltage applications
• High current capability up to 8.5A

Applications

• Low voltage point-of-load regulation
• Battery-powered systems requiring efficient step-down conversion
• Embedded systems with 4V to 16V input rails

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific tape-and-reel packaging requirements for surface mount assembly processes. Ensure supply chain stability due to potential limited availability or obsolescence risks associated with legacy Linear Technology products.

Selection Notes

Select this component when a high-current synchronous buck regulator is needed for outputs below 2.5V. It serves as a drop-in replacement for the LT1506 in designs requiring improved performance at lower voltages. Consider thermal management requirements given the 8.5A output capability in an SOIC-8 package.

Part Context

This part belongs to the LT1959 series of switching regulators manufactured by Analog Devices (formerly Linear Technology). It is designed for applications requiring robust step-down conversion with high efficiency. The #TRPBF suffix indicates tube-free tape and reel packaging suitable for automated pick-and-place manufacturing.
