LM2852XMXAX-1.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2852XMXAX-1.0/NOPB is a synchronous step-down DC-DC converter from Texas Instruments, part of the SIMPLE SWITCHER family. It delivers a fixed 1.0V output with a maximum current capability of 2A. The device operates within an input voltage range of 2.85V to 5.5V and supports switching frequencies of 500kHz or 1.5MHz. It is housed in a 14-pin HTSSOP package with an exposed pad for thermal management. The component functions reliably across an extended junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the ordering suffix /NOPB confirms lead-free compliance and RoHS adherence as per manufacturer specifications. Confirm the specific pinout and thermal pad requirements match the target PCB layout. Ensure the fixed 1.0V output aligns with the load requirements, as adjustable variants are available if different voltages are needed. Cross-reference the package dimensions against the mechanical outline drawing provided in the official datasheet.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.0V output is required for space-constrained designs. The choice between 500kHz and 1.5MHz depends on the trade-off between inductor size and ripple current. Verify that the input voltage remains within the 2.85V to 5.5V window under all operating conditions. Consider the thermal performance of the HTSSOP package relative to the expected load current and ambient temperature constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This regulator belongs to the LM2852 series of synchronous buck converters designed for compact power solutions. It shares architectural similarities with other members like the LM2852YMXAX-3.3/NOPB but differs in its fixed output voltage setting.
