LM2852XMXAX-1.8/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2852XMXAX-1.8/NOPB is a synchronous step-down DC-DC converter from Texas Instruments, housed in a 14-pin HTSSOP package with an exposed pad. It delivers a fixed 1.8V output at up to 2A load current. The device operates with an input voltage range of 2.85V to 5.5V and supports adjustable switching frequencies between 500kHz and 1500kHz. It features factory-programmed EEPROM settings for output voltages ranging from 0.8V to 3.3V in 100mV increments. The component functions within an operating temperature range of -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including the suffix 'NOPB' to confirm lead-free compliance and RoHS status. Ensure the specific output voltage variant matches the design requirement, as the LM2852 series offers multiple fixed voltage options. Confirm the package type is the 14-HTSSOP with thermal pad for proper PCB layout and thermal dissipation planning.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.8V output is required with up to 2A continuous current capability. Consider the wide input voltage range suitable for single-cell lithium battery or 5V rail applications. Evaluate the need for factory-programmed voltage accuracy versus adjustable resistor networks found in other variants. Check thermal requirements for the HTSSOP package under maximum load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2852 family of Simple Switcher buck regulators. It shares core architecture with variants like LM2852XMXAX-3.3/NOPB but differs in its factory-set output voltage. The 'X' in the part number typically denotes specific packaging or tape-and-reel configurations. It competes in the low-to-medium power synchronous buck regulator market segment.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2852XMXAX-3.3/NOPB offers identical electrical characteristics except for a fixed 3.3V output instead of 1.8V. LM2852YMXAX-1.8/NOPB may offer similar performance with potential minor pinout or feature variations; verify datasheet compatibility before substitution.
