BD9107FVM-TR

Overview

The BD9107FVM-TR is a synchronous buck converter manufactured by ROHM Semiconductor, designed for step-down voltage regulation. It operates with an input voltage range of 4 V to 5.5 V and provides a single adjustable output voltage between 1 V and 1.8 V. The device delivers a maximum output current of 1.2 A at a fixed switching frequency of 1 MHz. Key electrical specifications include a typical quiescent current of 10 uA and a supply current of 250 uA during operation. It is housed in an MSOP-8 package and functions within a temperature range of -25°C to +85°C.

Feature Summary

• Integrates synchronous rectification using internal N-channel and P-channel FETs for high efficiency across load ranges.
• Employs current mode PWM control architecture to ensure rapid transient response during sudden load changes.
• Includes Simple Light Load Mode (SLLM) technology to maintain high efficiency under light load conditions.

Applications

• Generating low voltage rails from 5V or 3.3V power lines for portable electronics.
• Powering logic circuits and microcontrollers in standard-grade industrial applications.
• Voltage regulation for peripheral components in consumer devices requiring stable 1V to 1.8V supplies.

Procurement Notes

Verify the component status as NRND (Not Recommended for New Designs) before initiating procurement. Confirm that the MSOP-8 package dimensions and pinout match the design requirements. Ensure compliance with RoHS directives if applicable to the target market. Review the official datasheet for thermal dissipation limits and layout guidelines specific to the synchronous buck topology.

Selection Notes

Select this component when a compact solution is needed for converting 5V inputs to lower voltages like 1.2V or 1.5V. The 1.2 A output capability suits moderate load applications. Consider the 1 MHz switching frequency for smaller external passive components. Verify that the -25°C to +85°C operating range meets the environmental constraints of the final assembly.

Part Context

This part belongs to the BD9107FVM series of high-efficiency step-down switching regulators from ROHM. It is categorized under PMIC - Power Management ICs. The device utilizes a synchronous buck topology to efficiently manage power conversion. It is distinct from linear regulators due to its switching nature and higher efficiency profile.
