illustrate

The LM2611 is a current-mode PWM inverter switching regulator. The 2.7 operating system is regulated from a one-14V power supply, which is capable of producing a negative output voltage regulation to -(36-V (max)). The input and output inductors of the LM2611 are adopted, enabling low voltage ripple and RMS pairs of input and output currents. With a switching frequency of 1.4MHz, inductors and output capacitors can be physically small and cost-effective. The high efficiency is achieved by using a FET with low R DS (day).

The LM2611 has a shutdown pin that can be activated to save battery life by reducing some of the unwanted IQ. 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:
