LM10506TMX/NOPB

Power Management - Specialized Overview

The LM10506TMX/NOPB is a Texas Instruments power management IC featuring three synchronous buck converters and one low-dropout regulator. It operates with an input voltage range of 3 V to 5.5 V and integrates a fixed switching frequency of 2 MHz. The device provides four output channels with current capabilities of 400 mA, 600 mA, and 1.3 A. Output voltages are adjustable from 700 mV to 1.335 V for the buck regulators and 1.1 V to 3.6 V for the LDO. It functions within a temperature range of -40°C to +85°C in a DSBGA-34 package.

Power Management - Specialized Feature Summary

• Integrates three high-efficiency synchronous buck converters and one LDO linear regulator into a single compact unit.
• Utilizes a fixed 2 MHz switching frequency to minimize external component size while maintaining stable regulation.
• Features a low quiescent current of 100 uA to enhance system efficiency during standby or light-load conditions.

Power Management - Specialized Applications

• Portable electronic devices requiring multi-rail power distribution
• Embedded systems with strict space constraints
• Battery-powered equipment needing efficient voltage conversion

Power Management - Specialized Procurement Notes

Verify the NRND status before procurement, as this indicates the component is not recommended for new designs. Confirm that the DSBGA-34 package compatibility matches your PCB layout requirements. Ensure the operating temperature range meets your specific environmental conditions. Cross-reference the exact suffix to guarantee pinout and electrical specifications align with your schematic needs.

Power Management - Specialized Selection Notes

Select this component when a compact solution for multiple voltage rails is required. It is suitable for applications where board space is limited due to its integrated topology. Consider the 2 MHz frequency for smaller inductor sizes. Verify that the input voltage range covers your supply variations. Check if the available output currents meet the load demands of all connected subsystems.

Power Management - Specialized Part Context

This part belongs to the LM10506 series of power management ICs from Texas Instruments. It is designed to replace discrete regulator solutions by integrating multiple converters. The series targets applications requiring high density and efficiency. Other variants may offer different package options or slight electrical parameter adjustments.

Power Management - Specialized Replacement Considerations

Publicly confirmed substitute part numbers include LM10506TMX-A-NOPB, LM10506TMX-A/NOPB, and LM10506TMX-NOPB. These variants share the same core functionality and pinout but may differ in specific manufacturing revisions or minor electrical characteristics. Verify datasheet details for each candidate before substitution.
