LP3907TL-PLNTO/NOPB

Overview

The LP3907TL-PLNTO/NOPB is a Texas Instruments PMIC featuring four outputs: two synchronous buck converters and two LDOs. It operates on a 2.8V to 5.5V supply with a 2.1MHz switching frequency. Output 1 provides 1A at 1.3V, Output 2 delivers 600mA at 2.2V, and Output 3 supplies 300mA at 2.9V. The device includes sequencing control and is housed in a 25-WFBGA package, operating between -40°C and +85°C.

Feature Summary

• Integrates dual high-current synchronous step-down DC/DC converters and dual low-dropout linear regulators for efficient power distribution.
• Features built-in sequencing control to manage the startup order of multiple voltage rails for system stability.
• Supports I2C-compatible interface for programmable configuration and monitoring of regulator parameters.

Applications

• Advanced application processors requiring multi-rail power sequences
• Field Programmable Gate Array (FPGA) core and I/O power systems
• Generic embedded systems with mixed analog and digital load requirements

Procurement Notes

Verify the specific suffix PLNT against the manufacturer's current datasheet to confirm pinout and thermal pad configurations. Ensure the 25-WFBGA footprint matches your PCB design guidelines. Confirm RoHS compliance status via official documentation before finalizing procurement specifications.

Selection Notes

Select this component when a single IC solution is needed to reduce board space for applications requiring both high-current switching regulation and low-noise linear regulation. The integrated sequencing feature simplifies design complexity compared to using discrete controllers. Verify that the required output voltages align with the fixed options provided in the datasheet.

Part Context

This part belongs to the LP3907 family of specialized power management ICs from Texas Instruments. The series is designed to consolidate multiple power stages into a compact form factor, targeting portable and embedded electronics where space efficiency and power integrity are critical design constraints.

Replacement Considerations

LP3907SQ-PJXIX/NOPB offers similar functionality but utilizes a 24-WQFN package instead of the 25-WFBGA. Designers must evaluate pin compatibility and thermal dissipation differences before substituting these components in existing designs.
