LM2830ZMFX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2830ZMFX/NOPB is a high-frequency step-down DC-DC switching regulator manufactured by Texas Instruments. It operates with an input voltage range of 3 V to 5.5 V and provides a fixed output voltage of 1.2 V. The device delivers up to 1 A of load current and integrates a 3 MHz switching frequency to minimize external component size. It features adjustable soft-start, cycle-by-cycle current limiting, and thermal shutdown protection. The component is housed in a compact SOT-23-5 package and supports operation across a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a power switch for efficient buck conversion within a minimal footprint
• Provides built-in protection mechanisms including thermal shutdown and current limiting
• Utilizes high-frequency operation to reduce the required size of passive components

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered consumer electronics
• Embedded systems requiring regulated low-voltage power rails

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'ZMF' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Confirm availability as the base part number may be discontinued or subject to long lead times. Ensure the ordering code matches the exact voltage and package requirements for your design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.2 V output is required from a 3 V to 5.5 V source. It is suitable for designs prioritizing small board space due to the 3 MHz switching frequency. Consider alternative models if variable output voltage or higher current capacity beyond 1 A is needed.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2830 family of synchronous buck converters. It shares architectural similarities with other TI regulators like the LM2831 but differs in switching frequency and current capabilities. The 'NOPB' suffix indicates lead-free construction and compliance with environmental standards.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for direct substitutes such as LM2830ZMF or LM2830ZMFX/NOPB variants. Verify that any replacement maintains the 1.2 V output and SOT-23-5 package form factor.
