LM2733YMFX Description

Short technical summary and product information.

The LM2733YMFX from Texas Instruments is a current-mode boost converter designed for high power density applications. It operates at a fixed switching frequency of 600 kHz, utilizing an internal 1A DMOS FET switch with a 40V rating.

 

This device supports a wide input voltage range from 2.7V to 14V and is capable of boosting to voltages of 16V or greater. The low shutdown current of less than 1 µA makes it suitable for power-sensitive designs. The converter is internally compensated and features cycle-by-cycle current limiting for robust operation.

 

Packaged in a compact 5-pin SOT-23 (SC-74A, SOT-753) surface-mount package, the LM2733YMFX allows for the use of small external components like capacitors and inductors. Its operating temperature range is -40°C to 125°C (TJ). The adjustable output type and positive output configuration make it versatile for various power management needs.
