LP3910SQ-AM/NOPB

Power Management - Specialized Overview

The LP3910SQ-AM/NOPB is a specialized Power Management IC (PMIC) designed for hard drive-based portable media players and handheld mobile devices. Manufactured by Texas Instruments, it operates within a supply voltage range of 2.5V to 6V and features a low operating supply current of 30 µA. The component supports an output current of 600 mA and functions reliably across an extended temperature range from -40°C to +85°C. It is housed in a compact 48-WQFN (6x6 mm) package with an exposed pad, suitable for surface-mount technology.

Power Management - Specialized Feature Summary

• Integrated power management solution tailored for portable media player architectures
• Low quiescent current consumption for extended battery life
• Robust thermal performance with exposed pad design

Power Management - Specialized Applications

• Hard drive-based portable media players
• Handheld mobile devices
• Portable consumer electronics requiring integrated PMIC

Power Management - Specialized Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Confirm the specific suffix 'AM' against official datasheets to ensure correct pinout and functionality. Check product status, as this part may be obsolete or superseded by newer revisions. Ensure RoHS compliance documentation matches the NOPB designation. Cross-reference ordering information with authorized distributors to avoid counterfeit components.

Power Management - Specialized Selection Notes

Select this component when designing power systems for legacy hard-drive-based portable media players. It provides a consolidated solution for multiple power rails required by such devices. Consider the 48-pin WQFN package constraints during PCB layout. Evaluate if the 600 mA output capability meets the peak load requirements of the target application. Verify compatibility with the 2.5V to 6V input supply range available in the system.

Power Management - Specialized Part Context

This device belongs to the LP3910 series of specialized PMICs developed for portable entertainment devices. It integrates multiple power regulators and control logic into a single chip to reduce board space and component count. The series was widely used in early-generation portable media players before the shift to flash-storage-only devices. The SQ variant indicates industrial temperature grading.
