LM2611 1.
4MHz Cuk Converter
General Description
The LM2611 is a current mode, PWM inverting switching
regulator.
Operating from a 2.
7 - 14V 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.
With a switching frequency of 1.
4MHz, the inductors and output capacitor can be physically small and low cost.
High efficiency is achieved through the use of a low RDS(ON) FET.
The LM2611 features a shutdown pin, which can be activated when the part is not needed to lower the Iq and save...
