LTC3830EGN#PBF

DC DC Switching Controllers Overview

The LTC3830EGN#PBF is a synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 3V to 5.5V and supports output voltages from 0.6V to VIN. The device features a fixed switching frequency of 200kHz and includes programmable soft-start functionality. Packaged in an 8-lead SSOP, it is designed for high-efficiency power management applications requiring precise voltage regulation.

DC DC Switching Controllers Feature Summary

• Synchronous buck topology utilizing external N-channel MOSFETs for high efficiency
• Fixed 200kHz switching frequency with internal compensation
• Integrated soft-start capability to limit inrush current during startup

DC DC Switching Controllers Applications

• Point-of-load regulation for digital signal processors
• Power supply stages for embedded memory systems
• General-purpose low-voltage DC/DC conversion

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence when sourcing. Confirm package integrity upon receipt as surface-mount components are sensitive to mechanical stress. Ensure ESD precautions are maintained during handling and assembly processes to prevent latent damage to the control circuitry.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring a fixed 200kHz frequency to simplify filter design. It is suitable for single-output applications where input voltages remain between 3V and 5.5V. Consider thermal performance of external MOSFETs as the controller drives them directly without integrated switches.

DC DC Switching Controllers Part Context

This part belongs to the LTC3830 family of synchronous buck controllers. It shares architectural similarities with other members like the LTC3831 but differs in pinout and specific feature sets tailored for different memory termination or general power needs within the Analog Devices portfolio.

DC DC Switching Controllers Replacement Considerations

LTC3830ES8#TRPBF is a documented direct substitute offering identical electrical specifications in an SOIC-8 package.
