LM2611AMF/NOPB

The LM2611AMF/NOPB is a Cuk Converter operates from a 2.7 to 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 converter 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.

• Low RDS (ON) DMOS FET
• Better regulation than a charge pump
• Uses tiny capacitors and inductors
• <lt/>1µA Low shutdown current
• Green product and no Sb/Br
