The LM2611BMF/NOPB is a current-mode PWM inverting Switching Regulator for use with LCD bias. Operating from a 2.7 to 4V supply, it is capable of producing a regulated negative output voltage of up to -(36VIN(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 inductor and output capacitor can be physically small. 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 battery life. A negative feedback (NFB) pin provides a simple method of setting the output voltage, using just two resistors. Cycle-by-cycle current limiting and internal compensation further simplify the use of the LM2611.
● Low RDS(ON) DMOS FET
● Better regulation than a charge pump
● Uses tiny capacitors and inductors
● 1mVp-p Output ripple
● -5V at 300mA from 5V Input
● <1µA Low shutdown current
