LM2734XMFX

Voltage Regulators - DC DC Switching Regulators Overview

The LM2734XMFX is a high-efficiency, synchronous step-down DC-DC converter from National Semiconductor. It integrates two N-channel power MOSFETs and operates with an input voltage range of 2.7V to 5.5V. The device delivers up to 1.5A output current with adjustable output voltages. It features a fixed 1.2MHz switching frequency to minimize external component size. The controller employs constant-frequency peak current mode control for fast transient response. It includes comprehensive protection features such as thermal shutdown and cycle-by-cycle current limiting.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated synchronous rectification with dual N-channel MOSFETs for enhanced efficiency
Fixed 1.2MHz switching frequency enabling compact passive component selection
Constant-frequency peak current mode control architecture for stable operation
Built-in thermal shutdown and cycle-by-cycle current limiting for robustness

Voltage Regulators - DC DC Switching Regulators Applications

Portable electronics requiring efficient power management
Battery-powered devices with single-cell lithium-ion inputs
Embedded systems needing regulated low-voltage rails
Industrial control modules with 3.3V or 5V logic requirements

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'XMFX' corresponds to the tape-and-reel packaging configuration and temperature grade. Confirm that the manufacturer designation aligns with Texas Instruments following the acquisition of National Semiconductor. Ensure compatibility with standard PCB footprints for the MSOP-10 package before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when input voltages remain between 2.7V and 5.5V and output currents up to 1.5A are required. The fixed 1.2MHz frequency suits applications prioritizing small inductor size over ultra-low noise. Consider alternative models if higher output currents or wider input ranges are necessary. Evaluate thermal performance based on expected ambient conditions and PCB copper area availability.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2734 family of synchronous buck converters designed for space-constrained applications. The 'X' indicates the MSOP-10 package type, while 'MFX' specifies the reel quantity and packaging variant. These devices were originally developed by National Semiconductor before being integrated into Texas Instruments' portfolio.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other synchronous buck converters from the same family with compatible pinouts. Verify equivalent electrical characteristics such as switching frequency and current limits. Check for package compatibility to ensure seamless PCB integration without redesigning the footprint layout.
