LM2852YMXA-1.2/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2852YMXA-1.2/NOPB is a synchronous step-down DC-DC converter from Texas Instruments' SIMPLE SWITCHER family. It operates with an input voltage range of 2.85V to 5.5V and provides a fixed 1.2V output at up to 2A. The device supports switching frequencies of 500kHz or 1500kHz, enabling compact passive component selection. Packaged in a 14-pin HTSSOP with exposed pad for thermal dissipation, it functions within a junction temperature range of -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix configuration against the manufacturer's current datasheet to ensure compatibility with required switching frequency settings. Confirm package integrity upon receipt, as the exposed pad requires proper soldering techniques for thermal performance. Cross-reference ordering information with official TI documentation to avoid discrepancies in pinout or electrical characteristics.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.2V output is required from a 3.3V or 5V source. Evaluate the trade-off between 500kHz and 1500kHz frequencies based on available board space for inductors and capacitors. Ensure the application load does not exceed the 2A continuous current rating while maintaining adequate thermal management through the exposed pad.
