LM2731YMF

Voltage Regulators - DC DC Switching Regulators Overview

The LM2731YMF is a step-up switching regulator manufactured by Texas Instruments, formerly National Semiconductor. It operates as a boost converter with an internal 22V DMOS FET switch. The device supports selectable switching frequencies of 0.6 MHz or 1.6 MHz to optimize efficiency and external component size. It accepts input voltages from 2.7 V to 14 V and provides adjustable output voltages up to 22 V. The maximum output current is rated at 1.5 A. It utilizes current-mode control with pulse width modulation in a five-pin SOT-23 package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a high-voltage DMOS power switch for compact design
Features selectable switching frequency for efficiency optimization
Supports wide input voltage range suitable for battery applications
Includes shutdown capability to minimize quiescent current

Voltage Regulators - DC DC Switching Regulators Applications

Portable consumer electronics requiring voltage boosting
Battery-powered systems needing regulated higher voltage rails
General-purpose DC-DC conversion in space-constrained designs

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and electrical characteristics. Ensure the component source matches Texas Instruments specifications. Confirm RoHS compliance status if required by project constraints. Validate the package type corresponds to the SOT-23-5 footprint during integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact boost solution is required with inputs between 2.7 V and 14 V. The choice depends on whether 0.6 MHz or 1.6 MHz operation better suits the inductor size and efficiency requirements. Consider the 22V switch rating for output voltage headroom. Evaluate thermal performance within the small SOT-23 package for the expected load current.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2731 family of boost converters. It shares architectural similarities with the LM2733 but features a lower 22V switch rating compared to the 40V variant. The YMFX designation indicates a tape-and-reel packaging format. It serves as a direct replacement for older National Semiconductor versions with updated manufacturing standards.
