LM2852YMXA-0.8/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2852YMXA-0.8/NOPB is a synchronous step-down DC-DC converter manufactured by Texas Instruments, originally part of the National Semiconductor portfolio. It operates with an input voltage range of 2.85V to 5.5V and provides a fixed output voltage of 0.8V. The device delivers up to 2A of continuous output current and supports switching frequencies of 500kHz or 1500kHz. It is housed in a 14-pin HTSSOP package with an exposed pad for thermal management.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Synchronous buck topology integrates high-side and low-side power switches for improved efficiency
• Fixed internal switching frequency options allow optimization for size and transient response
• Integrated compensation network simplifies external component count
• Thermal performance enhanced via exposed pad design in HTSSOP package

Voltage Regulators - DC DC Switching Regulators Applications

• Portable electronics requiring efficient voltage regulation from single-cell lithium batteries
• Embedded systems needing stable low-voltage power rails for logic circuits
• Industrial control modules operating within standard automotive voltage ranges

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer origin as Texas Instruments acquired National Semiconductor's analog business. Confirm the suffix indicates lead-free and RoHS compliance. Ensure the package matches the 14-pin HTSSOP EP specification. Cross-reference the fixed 0.8V output requirement against application needs before ordering.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 0.8V output is required from a 3.3V or 5V source. The 2A current capability suits moderate load applications. Choose between 500kHz and 1500kHz variants based on inductor size constraints and transient response requirements. The synchronous design offers better efficiency than non-synchronous alternatives at similar current levels.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2852 family of synchronous buck regulators. It shares architectural similarities with other members like the LM2852XMXA series but differs in fixed output voltage settings. The family targets portable and embedded applications requiring compact solutions with high efficiency.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2852YMXA-1.3/NOPB and LM2852YMXA-1.5/NOPB if different output voltages are acceptable. Verify pin compatibility and thermal characteristics when replacing with other LM2852 variants.
