• Includes built-in USB transceiver functionality for connectivity
• Features high-speed serial interface for system control

Power Management - Specialized Applications

• Cellular handsets
• CDMA mobile devices

Power Management - Specialized Procurement Notes

Verify the specific suffix 'M' against the manufacturer's current product status documentation to confirm availability and design recommendations. Ensure the 49-DSBGA package dimensions align with the target PCB layout constraints. Cross-reference the electrical specifications with the official datasheet to validate compatibility with the 3V supply requirement.

Power Management - Specialized Selection Notes

Select this component when a consolidated power management solution is required for CDMA or cellular phones. The integration of nine LDOs and two buck converters reduces board space compared to discrete solutions. Consider the 49-DSBGA package size for compact mobile designs requiring high integration density.

Power Management - Specialized Part Context

This part belongs to the Texas Instruments PMIC family tailored for mobile communications. It replaces older discrete regulator arrangements by combining linear and switching regulation stages. The inclusion of a USB transceiver distinguishes it from standard regulator arrays, offering a complete power subsystem for handheld devices.
