BD8165MUV-E2

Power Management - Specialized Overview

The BD8165MUV-E2 is a multi-channel system power supply IC designed for large panel TFT-LCD displays. It integrates one 3A FET boost DC/DC converter, two 2A FET buck DC/DC converters, two LDOs (500mA and 100mA), one VCOM amplifier, and positive/negative charge pumps. The device operates with an input voltage range of 4.2V to 18V and supports a switching frequency up to 0.65MHz. It features variable output logic voltages, a startup sequence circuit, and a VCOM channel. The component is housed in a VQFN-48 package (7.0x7.0mm) and functions within a temperature range of -40°C to +105°C.

Power Management - Specialized Feature Summary

• Integrates multiple power stages including boost, buck, and LDO regulators for comprehensive panel power management.
• Includes dedicated VCOM amplifier and charge pump circuits for LCD display driving requirements.
• Features configurable startup sequence and variable output logic voltages for flexible system integration.

Power Management - Specialized Applications

• TFT-LCD Display systems
• Large Panel Power Supply Applications

Power Management - Specialized Procurement Notes

Verify the current lifecycle status before procurement, as this component is marked as Not Recommended for New Designs (NRND). Confirm availability through authorized distributors, noting that stock may be limited or unavailable. Ensure the ordering suffix matches the required packaging format. Validate RoHS compliance and moisture sensitivity levels against specific project requirements prior to finalizing orders.

Power Management - Specialized Selection Notes

Select this IC for applications requiring a consolidated power solution for large TFT-LCD panels. It is suitable where space efficiency is critical due to its high integration level. Consider the 4.2V to 18V input range compatibility with existing system rails. Evaluate the thermal performance within the VQFN-48 package for the specific PCB layout constraints.

Power Management - Specialized Part Context

This part belongs to ROHM Semiconductor's specialized PMIC line for display applications. It is functionally related to other BD81xx series components but is distinct from smaller panel variants like the BD8184MUV-E2. The E2 suffix typically indicates environmental compliance updates compared to the base BD8165MUV model.

Power Management - Specialized Replacement Considerations

As the component is NRND, evaluate alternative PMICs from the same manufacturer family or competitors offering similar integration levels for large panels. Verify pin-to-pin compatibility if direct replacement is required, though no specific substitute part numbers are publicly confirmed for this exact configuration.
