LP8720TLX/NOPB

Overview

The LP8720TLX/NOPB is a specialized power management integrated circuit (PMIC) from Texas Instruments, designed for mobile applications. It integrates one step-down DC/DC converter and five linear regulators within a DSBGA-20 package. The device operates with an input voltage range of 2.7 V to 4.5 V. The buck converter supports output voltages from 800 mV to 2.3 V with a maximum output current of 400 mA. It features low quiescent current of 5 uA and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a single synchronous step-down DC/DC converter alongside five independent linear regulators in a compact footprint.
• Supports I2C compatible interface for configuration and control of regulator parameters.
• Optimized for low power consumption with minimal quiescent current during operation.

Applications

• Mobile phone power systems
• Smartphone baseband processors
• Portable multimedia devices

Procurement Notes

Verify the specific suffix 'TLX' indicates reel packaging when sourcing components. Confirm that the 'NOPB' designation ensures compliance with lead-free manufacturing standards as per Texas Instruments specifications. Ensure compatibility with the required DSBGA-20 surface mount assembly process. Cross-reference the manufacturer part number against official distributors to avoid counterfeit units. Validate thermal requirements for the intended operating environment.

Selection Notes

Select this component when a combined solution for buck conversion and multiple LDO outputs is required for space-constrained designs. Consider the 400 mA buck current limit and five LDO channels against system load profiles. Evaluate the wide operating temperature range suitability for harsh environments. Compare pinout and package dimensions against existing PCB layouts. Assess I2C interface availability on the host processor for control integration.

Part Context

This part belongs to the LP8720 series of PMICs from Texas Instruments. It is distinct from other variants like the LP8720TLE/NOPB which may differ in packaging or quantity options. The series targets high-integration needs in portable electronics, consolidating multiple power rails into a single chip to reduce board area and component count compared to discrete solutions.
