LTC1148HVCN-3.3#PBF

DC DC Switching Controllers Overview

The LTC1148HVCN-3.3#PBF is a high-efficiency synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates in a buck topology within a 14-pin PDIP package. The device provides a fixed 3.3 V output with a maximum current capability of 0.05 A. It supports an input voltage range from 3.5 V to 20 V and functions at a switching frequency of 250 kHz. The component is rated for operation between -40°C and +85°C, featuring a shutdown pin for power management.

• Integrated high-side and low-side transistor drivers
• Fixed 3.3 V output configuration
• Shutdown control capability

DC DC Switching Controllers Applications

• DC-DC switching controllers
• Current limiters
• Voltage regulators

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before integration. Confirm the 14-pin PDIP package availability matches your PCB footprint requirements. Check current supply status as distribution may be limited or subject to factory special orders. Ensure input voltage constraints align with your system's power source specifications.

DC DC Switching Controllers Selection Notes

Select this component when a fixed 3.3 V output is required from an input range up to 20 V. The synchronous design suits applications prioritizing efficiency over cost. Consider the through-hole PDIP package if surface-mount options are unsuitable. Verify that the 0.05 A output current meets load demands, as higher current variants exist in the series.

DC DC Switching Controllers Part Context

This part belongs to the LTC1148 family of high-efficiency synchronous buck converters. It shares architectural similarities with other members like the LTC1148HVIS-5#PBF but differs in output voltage and package type. The HVCN variant specifically denotes the high-voltage capable through-hole version, distinguishing it from SOIC surface-mount equivalents.

DC DC Switching Controllers Replacement Considerations

LTC1148HVIS-5#PBF offers similar synchronous buck functionality but in an SOIC-14 package with a 5 V output.
