Product Summary

The LM2661MMX is a switched capacitor voltage converter. The LM2661MMX CMOS charge-pump voltage converter inverts a positive voltage in the range of 1.5V to 5.5V to the corresponding negative voltage. The LM2661MMX uses two low cost capacitor to provide 100 mA of output current without the cost, size, and EMI related to inductor based converters. With an operating current of only 120 μA and operating efficiency greater than 90% at most loads, the LM2661MMX provides ideal performance for battery powered systems. The LM2661MMX may also be used as a positive voltage doubler.

Parametrics

LM2661MMX absolute maximum ratings: (1)Supply Voltage (V+ to GND, or GND to OUT): 6V; (2)LV: (OUT 0.3V) to (GND + 3V); (3)FC, OSC: The least negative of (OUT 0.3V) or (V+ -6V) to (V+ + 0.3V). V+ and OUT Continuous Output Current 120 mA; (4)Operating Junction Temperature Range: -40℃ to +85℃; (5)Storage Temperature Range: -65℃ to +150℃; (6)Lead Temperature: 300℃.

Features

LM2661MMX features: (1)Inverts or doubles input supply voltage; (2)Narrow SO-8 and Mini SO-8 Package; (3)6.5W typical output resistance; (4)88% typical conversioefficiency at 100 mA; (5)selectable oscillator frequency: 10 kHz/80 kHz; (6)low current shutdowmode.
