LP3907TL-JJ11/NOPB

Overview

The LP3907TL-JJ11/NOPB is a specialized power management integrated circuit (PMIC) from Texas Instruments, belonging to the LP3907 series. It integrates two synchronous buck converters and two low-dropout (LDO) regulators within a single package. The device features a switching frequency of 2.1 MHz and operates with an input voltage range of 2.8 V to 5.5 V. It provides four independent output channels: Output 1 delivers 1.3 V at 1 A, Output 2 supplies 2.2 V at 600 mA, and Output 3 provides 2.9 V at 300 mA. The component supports sequencing control and is housed in a 25-WFBGA package.

Feature Summary

• Integrates dual synchronous buck converters and dual LDOs for comprehensive power rail generation
• Supports programmable output sequencing to manage power-up and power-down transitions
• Operates with high efficiency via a fixed 2.1 MHz switching frequency
• Includes I2C interface for digital configuration and monitoring capabilities

Applications

• Advanced application processors requiring multiple regulated voltage rails
• Field Programmable Gate Array (FPGA) core and I/O power systems
• Generic portable electronic devices needing compact power solutions

Procurement Notes

Verify the specific suffix JJ11 against the manufacturer datasheet to confirm pin compatibility and thermal characteristics. Ensure the design accommodates the 25-WFBGA package requirements. Confirm RoHS compliance status if required by regional regulations. Cross-reference the ordering part number with official TI documentation to avoid substitution errors during manufacturing.

Selection Notes

Select this component when a compact solution is needed for multi-rail power architectures. It is suitable for designs requiring both high-current switching regulation and low-noise linear regulation. Consider the 2.1 MHz frequency for balancing component size and efficiency. Verify that the input voltage range aligns with the system supply. Check thermal performance requirements for the WFBGA package under maximum load conditions.

Part Context

This PMIC belongs to the LP3907 family, designed for space-constrained applications. It consolidates multiple power stages into one chip, reducing board area compared to discrete solutions. The integration of buck and LDO outputs allows for efficient core voltage generation alongside stable analog or I/O supplies. The series is targeted at mobile and embedded computing platforms.

Replacement Considerations

LP3907SQ-PFX6W/NOPB offers similar functionality but uses a WQFN-24 package instead of WFBGA. LP3907TLX-JJ11/NOPB shares the same electrical specifications but may differ in reel packaging quantity. Verify pin-to-pin compatibility and thermal pad connections before substituting.
