Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2831YSD/NOPB

LM2831YSD/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2831YSD/NOPB is a synchronous step-down DC-DC converter manufactured by Texas Instruments. It operates with an input voltage range of 3 V to 5.5 V and provides a single adjustable output from 600 mV to 4.5 V. The device delivers up to 1.5 A of output current at a fixed switching frequency of 550 kHz. It features a WSON-6 package, supports shutdown functionality, and operates within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated synchronous rectification for high efficiency in compact designs
Fixed internal switching frequency reduces external component count
Shutdown pin enables low-power standby modes

Voltage Regulators - DC DC Switching Regulators Applications

Portable battery-powered devices requiring efficient voltage regulation
Embedded systems with single-supply architectures
Point-of-load conversion for digital logic circuits

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'Y' confirms the 550 kHz switching frequency variant, distinct from other LM2831 models. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the WSON-6 package footprint matches the design layout requirements. Check for moisture sensitivity level (MSL) ratings if reflow soldering is planned.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 550 kHz frequency is required for EMI filtering compatibility. Compare against the LM2831ZSD/NOPB if a higher 3 MHz frequency is needed instead. Evaluate thermal performance based on the WSON-6 package size and expected load conditions. Verify input voltage stability within the 3 V to 5.5 V range for optimal operation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2831 family of high-frequency step-down converters. It shares core architecture with variants like the LM2831ZSD/NOPB but differs in switching frequency specifications. The series targets applications needing efficient power management in small form factors.
