Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2852YMXAX-1.8/NOPB

LM2852YMXAX-1.8/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2852YMXAX-1.8/NOPB is a synchronous step-down DC-DC converter from the SIMPLE SWITCHER family, manufactured by Texas Instruments following the acquisition of National Semiconductor. It operates with an input voltage range of 2.85V to 5.5V and provides a fixed 1.8V output at up to 2A. The device supports switching frequencies of 500kHz or 1500kHz and is housed in a 14-pin HTSSOP package with an exposed pad for thermal management.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated synchronous rectification for high efficiency
Fixed internal feedback network eliminates external resistors
Selectable switching frequency for design flexibility
Compact solution suitable for space-constrained designs

Voltage Regulators - DC DC Switching Regulators Applications

Portable electronic devices
Embedded systems power supplies
Industrial control modules
Communication equipment

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer origin as Texas Instruments due to the National Semiconductor brand history. Confirm the suffix /NOPB indicates lead-free and RoHS compliance. Ensure the specific output voltage variant matches the required 1.8V specification, as other variants exist within the same package.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.8V output is required without external resistor dividers. Consider the 14-pin HTSSOP package for thermal performance and board space. Evaluate the need for 500kHz versus 1500kHz operation based on inductor size constraints and EMI requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2852 series of highly integrated buck regulators. It replaces older National Semiconductor parts under the Texas Instruments portfolio. The device simplifies power supply design by integrating the controller, drivers, and synchronous MOSFETs into a single chip.
