LM2831YSD/J7002202

Voltage Regulators - DC DC Switching Regulators Overview

The LM2831YSD/J7002202 is a high-frequency synchronous step-down DC-DC regulator manufactured by Texas Instruments. It operates with an input voltage range of 3 V to 5.5 V and provides an adjustable output voltage from 0.6 V to 4.5 V. The device supports a maximum output current of 1.5 A and features a fixed switching frequency of 3 MHz. It is housed in a compact 6-WSON (3x3 mm) package with an exposed pad for thermal dissipation. The component functions within a junction temperature range of -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates synchronous rectification for improved efficiency in a small footprint
• Utilizes a fixed 3 MHz switching frequency to minimize external passive component size
• Includes internal soft-start circuitry to limit inrush current during startup

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered consumer electronics
• Embedded systems requiring efficient voltage regulation
• Industrial control modules with limited board space

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix J7002202 against official Texas Instruments documentation, as standard commercial variants typically use NOPB or no suffix. Confirm RoHS compliance status, as some legacy LM2831 variants are non-compliant. Ensure the supplier provides valid traceability for this specific marking code to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when board space is constrained due to its 6-WSON package. The 3 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Ensure the application requires an adjustable output voltage within the 0.6 V to 4.5 V range and can accommodate the 1.5 A load capability without exceeding thermal limits.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2831 family of high-frequency buck converters. It shares core electrical specifications with the LM2831YSD/NOPB but may differ in packaging or environmental compliance markings. The 'J' suffix often denotes specific tape-and-reel configurations or regional distribution codes rather than functional changes.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2831YSD/NOPB is a direct parameter-equivalent replacement. Other compatible options include the LMR10515 series for similar performance in different packages. Verify pinout compatibility and thermal requirements before substituting.
