Texas Instruments LP87334ERHDR

Overview

LP87334ERHDR from Texas Instruments is a programmable multi-output PMIC integrating two high-current buck converters and two LDO regulators. The device is designed for processor, camera, automotive-support, and embedded platforms that need software-configurable rails, dynamic voltage scaling, and power sequencing from a 28-pin VQFN package.

As part of the LP8733xx product family, LP87334ERHDR combines dual buck converters, dual LDO outputs, I2C-compatible control, dynamic voltage scaling, watchdog and power-good style supervision functions, and suffix-defined default configuration options. For engineers reviewing the LP87334ERHDR datasheet, LP87334ERHDR pinout, LP87334ERHDR application, or LP87334ERHDR equivalent, this device is widely used in application processors, camera modules, industrial embedded systems, automotive support electronics, FPGA auxiliary rails, and compact multi-rail power architectures.

Technical Context

In processor-based systems, LP87334ERHDR operates as a four-output PMIC. The two buck regulators provide efficient higher-current rails, while the two LDO regulators supply lower-current or lower-noise auxiliary rails.

The I2C-compatible interface supports register-based control of regulator settings, sequencing, and power-management functions. Dynamic voltage scaling allows rails to be adjusted during operation to balance performance and power consumption.

LP87334ERHDR is commonly used when a compact 28-pin RHD VQFN package, programmable rails, power sequencing, and LP8733 suffix-specific default configuration are required.

Key Specifications

Pinout & Package

The LP87334ERHDR pinout includes buck input and switch pins, LDO input/output pins, feedback or sense pins, I2C interface pins, enable/control pins, interrupt or status functions, and exposed-pad ground.

For PCB design, each buck switching loop should be compact, LDO output capacitors should be close to the pins, and I2C/control traces should be kept away from noisy switch nodes.

Key Features

• Two buck converters support processor rails.
• Two LDOs provide auxiliary or low-noise supplies.
• I2C control enables software-managed power states.
• Dynamic voltage scaling improves power efficiency.
• Power sequencing supports processor startup.
• 28-pin VQFN package supports compact layouts.

Applications

Equivalent & Alternatives

When evaluating a LP87334ERHDR equivalent, engineers should compare buck current, LDO count, I2C control, default configuration, package, dynamic voltage scaling, and sequencing requirements.

Compared with LP873220RHDRQ1, LP87334ERHDR should be selected when the LP8733 catalog configuration and RHD package match the design. LP87334ERHDR vs ADP5034ACPZ-R7 selection depends on I2C control, dynamic voltage scaling, rail current, package, and default voltage configuration.

Quality

LP87334ERHDR should be sourced as original Texas Instruments components through traceable supply channels. Quality checks may include VQFN package inspection, top-mark validation, solderability testing, output-voltage verification, and regulator load testing.

Production validation should include startup behavior, load transients, thermal performance, protection response, output ripple, and PCB layout review for the switching and linear regulator sections.

Availability

LP87334ERHDR available at Aetrix Electronics and is suitable for processor, camera, industrial embedded, automotive support, and FPGA auxiliary rail systems requiring stable power-management component supply support.

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 package, output-voltage option, rail-current budget, lifecycle status, lead time, and sourcing continuity helps reduce procurement risk.
