The Texas Instruments LM2611AMF is a current mode, PWM inverting switching regulator designed for efficient power conversion. It operates with an input voltage range of 2.7V to 14V and is capable of generating a regulated negative output voltage.
This Cuk converter features a switching frequency of 1.4MHz, which allows for the use of physically small and cost-effective inductors and capacitors. The device utilizes a low R DS(ON) DMOS FET for high efficiency. Key electrical specifications include a switch current limit of 1.2A and a typical quiescent current of 1.8 µA. The output ripple is as low as 1mVp-p under specific conditions (-5V at 300mA from a 5V input).
The LM2611AMF is housed in a compact 5-pin SOT-23-5 package, suitable for surface mounting. It includes features like a shutdown pin for power saving and cycle-by-cycle current limiting for protection. The operating temperature range is -40°C to 125°C (TJ).
This regulator is a good choice for applications requiring a negative voltage rail from a positive supply, offering better regulation than charge pumps and utilizing small external components.
