LM2611 - 1.4-MHz Cuk Converter

General Description

The LM2611 is a current mode, PWM inverting switching regulator.

Operating from a 2.7-V to 4-V supply, it is capable of producing a regulated negative output voltage of up to −(36 VIN(MAX)).

The LM2611 utilizes an input and output inductor, which enables low voltage ripple and RMS current on both the input and the output.
