LMR10530YSDX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LMR10530YSDX/NOPB is a Simple Switcher Nano Reg buck converter from Texas Instruments. It operates with an input voltage range of 3 V to 5.5 V and delivers up to 3 A output current. The adjustable output voltage spans from 600 mV to 4.5 V. Key electrical parameters include a switching frequency of 3 MHz, a typical quiescent current of 4.3 mA, and a shutdown feature. The device functions within a temperature range of -40°C to +125°C and is housed in a WSON-10 package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Fixed 3 MHz switching frequency enables compact external component sizing
• Shutdown pin allows for system power management and reduced standby consumption

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered electronics
• Point-of-load regulation for digital signal processors
• Industrial control systems requiring compact power solutions

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'YSDX' against the manufacturer's official datasheet to confirm packaging details and tape-and-reel specifications. Ensure the order matches the exact part number variant, as minor suffix differences may indicate different reel quantities or handling requirements. Cross-reference the RoHS status and lead-free designation with the latest product change notification documents provided by Texas Instruments.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3 MHz frequency is required to minimize passive component size compared to lower-frequency alternatives. The 3 A capability suits applications needing moderate current density in small footprints. Consider the 4.3 mA quiescent current if battery life is critical, noting it is higher than some ultra-low-power variants but offers higher performance density.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LMR10530 series of Simple Switcher Nano Regulators. It shares the same core topology and pinout with variants like the LMR10530XSD/NOPB, which differs primarily in switching frequency (1.5 MHz) and quiescent current characteristics. The series is designed for space-constrained applications requiring robust performance from a single-cell lithium-ion source.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LMR10530XSD/NOPB is a functional substitute within the same family, offering identical pinout and current ratings but operating at 1.5 MHz with lower quiescent current. Verify that the application can tolerate the lower switching frequency and adjusted thermal profile before substituting.
