LM2852XMXAX-3.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2852XMXAX-3.0/NOPB is a synchronous step-down DC/DC converter from the SIMPLE SWITCHER family, manufactured by Texas Instruments. It provides a fixed 3.0V output with a maximum load current of 2A. The device operates within an input voltage range of 2.85V to 5.5V and supports selectable switching frequencies of 500kHz or 1500kHz. It is housed in a 14-pin HTSSOP package with an exposed pad for thermal management and functions reliably across a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated synchronous rectification using internal high-side and low-side N-channel MOSFETs to maximize efficiency.
• Configurable switching frequency selection allows optimization between component size and transient response performance.
• Built-in protection mechanisms include cycle-by-cycle current limiting, thermal shutdown, and reverse battery protection.

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded processors and microcontrollers
• Battery-powered portable electronic devices requiring efficient step-down conversion
• Industrial control systems operating within standard 3.3V logic levels

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'XMXA' corresponds to the required tape-and-reel packaging configuration rather than tube packaging. Confirm that the 'NOPB' designation ensures compliance with current RoHS standards and absence of lead-based materials. Cross-reference the exact part number against the manufacturer's latest datasheet revision to ensure pinout compatibility and functional equivalence with previously sourced inventory.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.0V output is required without external feedback resistor networks. The choice depends on the need for integrated synchronous rectification to reduce external component count and board space. Consider the 1500kHz option if minimizing passive filter size is critical, while the 500kHz setting may offer better light-load efficiency in specific applications.

Voltage Regulators - DC DC Switching Regulators Part Context

This regulator belongs to the LM2852 series of SIMPLE SWITCHER power modules. The series is characterized by its compact form factor and ease of design implementation due to the integration of the controller and power switches. The LM2852X variant specifically denotes the fixed-output versions designed for straightforward deployment in space-constrained environments.

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 3.0V. LM2852YMXAX-3.0/NOPB serves as a direct functional substitute with equivalent performance specifications and pinout compatibility.
