LM2611AMFX Description

Short technical summary and product information.

The LM2611AMFX from Texas Instruments is a current mode, PWM inverting switching regulator designed for efficient power conversion. It operates with an input voltage range of 2.7 V to 14 V and can produce a regulated negative output voltage. The device utilizes a Cuk topology, incorporating input and output inductors to minimize voltage ripple and RMS current on both input and output.

 

With a high switching frequency of 1.4 MHz, the LM2611AMFX allows for the use of physically small and cost-effective inductors and output capacitors. It features a low R DS(ON) DMOS FET for high efficiency. The regulator includes a shutdown pin to conserve battery life when not in use and a negative feedback (NFB) pin for simple output voltage setting.

 

Key electrical specifications include a switch current limit of 1.2 A and a typical quiescent current of 1.8 µA. The output ripple is a low 1 mVp-p. The operating temperature range is -40°C to 125°C (TJ).

 

The LM2611AMFX is housed in a compact 5-pin SOT-23-5 package, suitable for surface mount applications. Its design simplifies usage with cycle-by-cycle current limiting and internal compensation.
