LTC1159IS-5#PBF

DC DC Switching Controllers Overview

The LTC1159IS-5#PBF is a synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4V to 40V and provides a fixed 5V output. The device supports up to 10A of output current with a typical switching frequency of 250kHz. Key electrical characteristics include a maximum load regulation of 60mV, a quiescent current of 20µA, and a shutdown feature. It is housed in a 16-pin SOIC package and functions as a high-efficiency DC-to-DC converter.

DC DC Switching Controllers Feature Summary

Synchronous buck topology for enhanced efficiency
Automatic Burst Mode operation for low-load performance
Integrated shutdown capability for power management

DC DC Switching Controllers Applications

High efficiency 12V to -12V 1A converters
Dual output 5V and 3.3V regulators
General purpose synchronous step-down switching regulators

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates tube packaging versus other variants. Confirm RoHS compliance status through official documentation. Ensure the operating temperature range meets system requirements. Check for obsolescence notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.

DC DC Switching Controllers Selection Notes

Select this component when a fixed 5V output is required from a wide input voltage range up to 40V. The 250kHz switching frequency allows for compact passive component selection. Consider the 10A current capability for moderate power applications requiring high efficiency at both heavy and light loads.

DC DC Switching Controllers Part Context

This part belongs to the LTC1159 series of synchronous step-down switching regulator controllers. The series is characterized by automatic Burst Mode operation to maintain high efficiencies at low output currents. It serves as a core power management IC for converting higher DC voltages to lower regulated levels efficiently.
