LM27313XMF/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM27313XMF/NOPB is a current-mode boost converter from Texas Instruments, housed in a compact SOT-23-5 package. It features an integrated 30V DMOS FET switch with a fixed switching frequency of 1.6 MHz. The device supports an input voltage range of 2.7 V to 14 V and provides an adjustable output voltage up to 28 V. It delivers a maximum output current of 800 mA. Key electrical parameters include a shutdown current of less than 1 µA and a quiescent operating current of 2.1 mA. The component operates within a temperature range of -40°C to +125°C and has a Moisture Sensitivity Level (MSL) of 1.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a high-voltage 30V internal DMOS FET switch within a minimal five-pin footprint.
• Utilizes a fixed 1.6 MHz switching frequency to enable the use of small external passive components.
• Includes built-in internal compensation to simplify circuit design and reduce external component count.
• Features comprehensive protection mechanisms including cycle-by-cycle current limiting and thermal shutdown.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable devices requiring step-up conversion from single-cell lithium-ion batteries.
• LCD bias voltage generation circuits.
• LED backlight driver power supplies.
• USB-powered module power chains.
• Small wireless communication equipment.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific suffix 'XMF' corresponds to the required tape-and-reel packaging quantity for your assembly line. Confirm that the non-automotive grade specification meets your project's reliability standards, as automotive applications require the Q1 variant. Ensure input voltage ranges align with your battery discharge curves before finalizing the order.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when board space is constrained but higher output voltages are necessary. The 1.6 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the load current does not exceed the 800 mA limit. Consider the LM27313-Q1 if AEC-Q100 certification is mandatory for the application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM27313 series of DC-DC converters designed for space-efficient power solutions. It shares architectural similarities with other TI boost regulators but distinguishes itself through the integration of a 30V switch in a SOT-23 package. The series targets applications where size reduction is critical without sacrificing output voltage capabilities.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM27313XMFX/NOPB serves as a direct functional substitute for the LM27313XMF/NOPB, differing only in lead-free compliance status. For automotive-grade requirements, the LM27313XQMFX/NOPB is the verified alternative. Other family members like the LM27313XSDX offer different packages or current ratings.
