SNOS965J – JUNE 2001 – REVISED DECEMBER 2015 LM2611 1.4-MHz Cuk Converter
1 Features 3 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. With a switching frequency
of 1.4 MHz, 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. 1 1.4-MHz Switching Frequency
Low RDS(ON) DMOS FET
