LP3907TLX-PLNTO/NOPB

Overview

The LP3907TLX-PLNTO/NOPB is a Texas Instruments PMIC featuring four outputs: two synchronous buck converters and two low-dropout (LDO) regulators. It operates with an input voltage range of 2.8V to 5.5V and includes an integrated sequencer. The device utilizes a 2.1MHz switching frequency and is housed in a 25-WFBGA package.

Feature Summary

• Integrates dual high-current step-down DC/DC converters and dual linear regulators within a single IC.
• Includes an internal power-good sequencer for controlled startup and shutdown timing.
• Features I2C-compatible interface for programmable control and monitoring.

Applications

• Advanced application processors
• Field Programmable Gate Arrays (FPGA)
• Portable electronic devices

Procurement Notes

Verify the manufacturer designation, as National Semiconductor was acquired by Texas Instruments. Confirm the specific suffix 'PLNTO' matches the required 25-WFBGA package and tape-and-reel configuration. Ensure compatibility with RoHS3 standards and check for any recent product change notices affecting availability or specifications.

Selection Notes

Select this component when a compact solution is needed for multi-rail systems requiring both efficient switching regulation and clean LDO outputs. The integrated sequencer simplifies board layout by managing power rail dependencies automatically. Verify that the 2.8V minimum input voltage aligns with the system's battery or supply characteristics.

Part Context

This part belongs to the LP3907 family of specialized power management ICs designed for portable applications. While originally associated with National Semiconductor, current production and documentation are managed by Texas Instruments following their acquisition. The device consolidates multiple power functions to reduce overall system footprint.
