Texas Instruments LP3907TL-JJ11/NOPB

Overview

LP3907TL-JJ11/NOPB from Texas Instruments / National Semiconductor is a multifunction programmable PMU integrating two step-down buck converters and two 300mA LDO regulators. The device is configured for 1.2V, 1.8V, 2.85V, and 2.85V rails, making it suitable for processors, FPGAs, DSPs, and compact portable systems that need four regulated supplies from one IC.

As part of the LP3907 product family, LP3907TL-JJ11/NOPB combines a 1A Buck1 rail, a 600mA Buck2 rail, two 300mA LDO rails, I2C-compatible control, preset startup configuration, buck mode selection, and compact DSBGA packaging. For engineers reviewing the LP3907TL-JJ11/NOPB datasheet, LP3907TL-JJ11/NOPB pinout, LP3907TL-JJ11/NOPB application, or LP3907TL-JJ11/NOPB equivalent, this device is widely used in low-power FPGAs, microprocessors, DSP platforms, portable media products, handheld instruments, and compact multi-rail embedded power architectures.

Technical Context

In processor and FPGA power trees, LP3907TL-JJ11/NOPB operates as a four-output PMU. Buck1 provides a 1.2V rail with 1A capability, Buck2 provides a 1.8V rail with 600mA capability, and the two LDO outputs provide 2.85V and 2.85V auxiliary rails at up to 300mA each.

The LP3907 architecture supports I2C register control while also offering datasheet-defined default output voltages and startup behavior. This orderable option uses Auto-Mode buck operation, EN_T delay code 010, and default UVLO Enabled.

LP3907TL-JJ11/NOPB is commonly used when a compact DSBGA PMU must supply digital core, I/O, analog, and peripheral rails with factory-defined voltage defaults and software-accessible control.

Key Specifications

Pinout & Package

The LP3907TL-JJ11/NOPB pinout includes buck input pins, buck switch nodes, LDO input and output pins, I2C interface pins, enable/startup timing pins, reset or status-related functions, and DSBGA ground connections.

For PCB design, each buck inductor and capacitor should be placed close to the DSBGA power pins, LDO output capacitors should be close to the load and PMU pins, and I2C traces should be routed away from switching nodes.

Key Features

• Dual buck converters support core and I/O rails.
• Two 300mA LDOs provide auxiliary or low-noise outputs.
• I2C-compatible control supports software power management.
• Factory-defined output voltages reduce external setting components.
• Compact DSBGA package supports dense portable layouts.
• Default UVLO and startup delay support controlled power-up.

Applications

Equivalent & Alternatives

When evaluating a LP3907TL-JJ11/NOPB equivalent, engineers should compare default output voltages, buck current, LDO current, I2C control, package, UVLO default, and startup timing.

Compared with LP8720TLX/NOPB, LP3907TL-JJ11/NOPB provides two buck rails and two LDO rails rather than one buck and five LDOs. LP3907TL-JJ11/NOPB vs ADP5034ACPZ-R7 selection depends on exact voltage defaults, I2C control requirements, package, and rail-current budget.

Quality

LP3907TL-JJ11/NOPB should be sourced as original Texas Instruments/National Semiconductor components through traceable supply channels. Quality checks may include DSBGA package inspection, top-mark validation, solderability review, and verification of all four factory-configured rails.

Production validation should include I2C communication, startup timing, buck load transients, LDO regulation, UVLO behavior, thermal performance, and output-voltage confirmation.

Availability

LP3907TL-JJ11/NOPB available at Aetrix Electronics and is suitable for FPGA, microprocessor, DSP, portable media, handheld, and compact embedded multi-rail power systems.

Supply support may include volume procurement planning, scheduled delivery arrangements, traceable sourcing management, and long-term supply support for OEM, industrial electronics, automotive electronics, and embedded product programs. Sample and NPI supply support, as well as urgent in-stock supply support, can also be arranged for prototype builds, pilot runs, and time-critical production needs.

For production builds, confirming output-voltage suffix, package, default startup behavior, lifecycle status, lead time, and sourcing continuity helps reduce procurement risk.
