BD9106FVM-TR

Overview

The BD9106FVM-TR is a synchronous buck switching regulator manufactured by ROHM Semiconductor, designed for industrial applications. It integrates N-channel and P-channel FETs within an MSOP-8 package to achieve high efficiency across the entire load range. The device operates with an input voltage of 4.5 V to 5.5 V and provides an adjustable output voltage from 1 V to 2.5 V at a maximum current of 0.8 A. It utilizes current-mode PWM control for fast transient response and includes Simple Light Load Mode (SLLM) technology. Key protection features include thermal shutdown, under-voltage lockout, and short-circuit protection with a time delay function.

Feature Summary

• Integrates synchronous rectifier Nch/Pch FETs for high efficiency
• Employs current-mode PWM control for rapid transient response
• Includes Simple Light Load Mode (SLLM) for optimized light-load performance
• Features built-in soft-start, thermal protection, UVLO, and timed short-circuit protection

Applications

• Industrial equipment power supplies
• Systems requiring long life cycle components
• Low voltage generation from 5V or 3.3V rails

Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status via official documentation before integration. Check for specific ordering suffixes that may indicate packaging variations. Ensure design compatibility with the specified MSOP-8 footprint and pin configuration. Review manufacturer notices regarding end-of-life status or recommended design alternatives.

Selection Notes

Select this component when a compact, high-efficiency step-down solution is required for 5V input systems. It is suitable for designs needing integrated FETs to minimize external component count. Consider its current-mode control for applications demanding quick load transient handling. Evaluate the SLLM feature if light-load efficiency is critical. Verify that the 0.8 A output current meets the target application's power requirements.
