LM2833XMYX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2833XMYX/NOPB is a step-down DC-DC switching regulator manufactured by Texas Instruments. It operates with an input voltage range of 3V to 5.5V and provides an adjustable output voltage from 0.6V to 4.5V. The device delivers a continuous output current of 3A at a fixed switching frequency of 1.5MHz. It is housed in a 10-pin MSOP PowerPad package (10-TFSOP, 10-MSOP) with an exposed thermal pad for heat dissipation. The component supports operation across a junction temperature range of -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'X' indicates cut tape packaging when ordering samples or small quantities. Confirm the 'NOPB' designation ensures lead-free compliance and RoHS adherence. Cross-reference the full part number with official Texas Instruments documentation to ensure compatibility with your design's thermal and electrical requirements before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 3A output current capability is required within a 3V to 5.5V input window. The 1.5MHz frequency is suitable for designs prioritizing smaller passive component sizes over ultra-low noise applications. Ensure the PCB layout accommodates the 10-MSOP PowerPad package for adequate thermal management during high-current operation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2833 family of synchronous buck converters. It shares architectural similarities with other TI regulators like the LM2831 but offers higher current capacity. The XMYX/NOPB designation specifies the MSOP PowerPad package, cut tape variant, and environmental compliance, distinguishing it from reel-based or non-powerpad versions.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct pin-compatible alternatives within the same family include the LM2833ZMY/NOPB. Verify that any substitute maintains the 3A current rating and 1.5MHz switching frequency to ensure circuit stability without redesigning the feedback network or inductor selection.
