LTC1148LCS#PBF

DC DC Switching Controllers Overview

The LTC1148LCS#PBF is a high-efficiency synchronous step-down switching regulator manufactured by Analog Devices (formerly Linear Technology). It operates with an input voltage range of 3.5V to 20V and provides a fixed 5V output at up to 2A current capability. The device utilizes surface-mount technology in a 16-lead SOIC package. Key electrical parameters include a switching frequency of up to 250kHz, 96% efficiency, and a maximum duty cycle of 100%. It is designed for applications requiring high power density and low noise.

DC DC Switching Controllers Feature Summary

• Synchronous buck topology for high efficiency
• Fixed 5V output configuration
• Surface-mount SOIC-16 packaging

DC DC Switching Controllers Applications

• Portable computer power supplies
• Hand-held equipment power systems
• Battery-powered devices requiring efficient DC-DC conversion

DC DC Switching Controllers Procurement Notes

Verify the manufacturer designation as Analog Devices Inc., noting that Linear Technology was acquired. Confirm the specific suffix #PBF indicates lead-free compliance. Check current availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the 16-lead SOIC package matches your PCB footprint requirements before ordering.

DC DC Switching Controllers Selection Notes

Select this component when a fixed 5V output is required from a 3.5V to 20V input source. It is suitable for designs prioritizing high efficiency (up to 96%) and compact size due to its 250kHz switching frequency. Compare against adjustable variants like the LTC1143 if variable output voltages are needed instead of the fixed 5V provided here.

DC DC Switching Controllers Part Context

This part belongs to the LTC1148 family of high-efficiency synchronous step-down regulators. These devices are engineered to minimize power drain and heat buildup in portable systems. The LCS variant specifically denotes the surface-mount package type, distinguishing it from through-hole options within the same functional family.
