LM2662/LM2663 Switched Capacitor Voltage Converter

Check for Samples: LM2662, LM2663

FEATURES

DESCRIPTION

The LM2662/LM2663 CMOS charge-pump voltage

converter inverts a positive voltage in the range of

1.5V to 5.5V to the corresponding negative voltage.

The LM2662/LM2663 uses two low cost capacitors to

provide 200 mA of output current without the cost,

size, and EMI related to inductor based converters.

With an operating current of only 300 μA and

operating efficiency greater than 90% at most loads,

the LM2662/LM2663 provides ideal performance for

battery powered systems. The LM2662/LM2663 may

also be used as a positive voltage doubler.

APPLICATIONS

•

Laptop computers

The oscillator frequency can be lowered by adding an

external capacitor to the OSC pin. Also, the OSC pin

may be used to drive the LM2662/LM2663 with an

external clock. For LM2662, a frequency control (FC)

pin selects the oscillator frequency of 20 kHz or 150

kHz. For LM2663, an external shutdown (SD) pin

replaces the FC pin. The SD pin can be used to

disable the device and reduce the quiescent current

to 10 μA. The oscillator frequency for LM2663 is 150

kHz.
