LM2852YMXA-1.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2852YMXA-1.0/NOPB is a synchronous step-down DC-DC converter from Texas Instruments, operating within an input voltage range of 2.85V to 5.5V. It provides a fixed output voltage of 1.0V with a maximum continuous output current capability of 2A. The device integrates high-side and low-side power switches and supports switching frequencies of 500kHz or 1500kHz. It is housed in a 14-pin HTSSOP package with an exposed pad (PWP) for thermal management. The component operates across an extended temperature range from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'YMXA' corresponds to the intended switching frequency option and package variant. Confirm that the 'NOPB' designation ensures lead-free compliance and RoHS adherence as per manufacturer specifications. Cross-reference the datasheet revision date to ensure compatibility with your design requirements. Ensure the ordering information matches the exact part number to avoid functional discrepancies related to output voltage or package type.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.0V output is required without external resistor networks. It is suitable for designs prioritizing board space savings through integrated power switches. Consider the 500kHz or 1500kHz frequency options based on inductor size constraints and EMI requirements. Ensure the application load does not exceed the 2A limit and that thermal dissipation capabilities of the HTSSOP package are adequate for the expected ambient conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2852 family of SIMPLE SWITCHER synchronous buck regulators. Other variants in the series offer different fixed output voltages such as 1.3V, 3.3V, and others, sharing the same pinout and control architecture. The family is designed for applications requiring compact solutions with high efficiency and robust protection features in a small form factor.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LM2852 variants with different fixed output voltages if the voltage requirement can be adjusted. For equivalent performance with adjustable outputs, consider the base LM2852 model. Verify pin compatibility and thermal characteristics before substituting with non-TI synchronous buck regulators.
