illustrate

The LM2611 is a current mode PWM inverter switching regulator. 2.7 Operating system from a one-14V power supply, it is capable of generating a negative output voltage regulated to - (36-V_(maximum)). The input and output inductors of the LM2611 are used to enable low voltage ripple and rms to input and output currents. With a switching frequency of 1.4MHz, inductors and output capacitors can be physically small and low cost. High efficiency is achieved by using a FET low R_{DS (day).}

The LM2611 has a shutdown pin, which can be activated when part is unwanted IQ reduction, saving battery life. The negative feedback (negative feedback) pin provides an easy way to set the output voltage with only two resistors. Cycle limiting cycle-by-cycle current and internal compensation further simplify the use of the LM2611.

The LM2611 is available in a small SOT23-5 package. It has two levels:

	Grade A	Grade B
Current limit	1.2A	Adjustable to 0.9A;
targetRDS(ON).	0.5	0.7
