LP3907TL-JJCP/NOPB

Overview

The LP3907TL-JJCP/NOPB is a Texas Instruments PMIC featuring two synchronous buck converters and two low-dropout (LDO) linear regulators. It operates within an input voltage range of 2.8V to 5.5V. The device integrates four outputs, including a 1A buck channel, a 600mA buck channel, and two LDO channels rated at 300mA each. It utilizes a 25-WFBGA package with dimensions of 4mm x 4mm. The component supports an operating temperature range from -40°C to 85°C and includes sequencing capabilities for power management applications.

Feature Summary

• Integrates dual synchronous step-down DC/DC converters and dual linear regulators in a single compact package
• Supports programmable output sequencing for controlled power-up and power-down sequences
• Operates with a wide input voltage range suitable for battery-powered systems
• Includes protection features such as thermal shutdown and current limiting

Applications

• Portable consumer electronics requiring multiple voltage rails
• Mobile communication devices needing efficient power management
• Embedded systems with strict space constraints
• Battery-operated equipment requiring extended runtime

Procurement Notes

Verify the specific suffix JJCP against the manufacturer's official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the 25-WFBGA package footprint aligns with your PCB layout. Confirm RoHS compliance status if required by your manufacturing standards. Check for any recent product change notifications that may affect availability or specifications.

Selection Notes

Select this component when a compact solution combining switching and linear regulation is needed. The integrated sequencer simplifies board design compared to discrete solutions. Consider the 2.1MHz switching frequency for smaller external components. Verify that the total output current requirements fit within the specified limits for each regulator channel.
