LM2852XMXA-1.2

Voltage Regulators - DC DC Switching Regulators Overview

The LM2852XMXA-1.2 is a synchronous step-down DC/DC converter from Texas Instruments, part of the SIMPLE SWITCHER family. It integrates high-side and low-side N-channel power MOSFETs to deliver a fixed 1.2V output at up to 2A. The device supports adjustable switching frequencies of 500kHz or 1500kHz via an external resistor. It operates with an input voltage range of 2.85V to 5.5V. The component is housed in a 14-pin HTSSOP package and functions within a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'XMXA' against the manufacturer's current datasheet to confirm pinout and electrical characteristics. Ensure the absence of '/NOPB' indicates lead-free compliance status if required by assembly specifications. Cross-reference the exact part number with official TI documentation to avoid confusion with similar variants in the LM2852 series.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.2V output is required without external feedback resistors. The choice depends on the need for integrated synchronous rectification to minimize external component count. Consider the 500kHz or 1500kHz frequency options based on inductor size constraints and transient response requirements. Verify that the input voltage remains within the 2.85V to 5.5V operational window.
