The LM2731XMF from Texas Instruments is a highly efficient, current-mode boost converter designed for power management applications. It features a 22-V internal DMOS FET switch capable of handling up to 1.8 A, making it suitable for boosting voltages up to 20 V.
This device operates over a wide input voltage range of 2.7 V to 14 V and offers an adjustable output voltage. It supports fixed switching frequencies of 1.6 MHz (X option) and 600 kHz (Y option), enabling the use of tiny capacitors and inductors for high power density.
The LM2731XMF is housed in a compact 5-lead SOT-23 package, ideal for space-constrained designs. Its features include cycle-by-cycle current limiting and internally compensated circuitry, simplifying design and improving reliability. The low shutdown current of less than 1 µA further enhances its suitability for battery-powered applications.
Key electrical characteristics include a switch current limit of 1.5 A typical, a maximum duty cycle of 93%, and a quiescent current of 2 µA typical. The operating temperature range is -40°C to 125°C (TJ).
