Frequently Asked Questions
How can I achieve a low current shutdown mode?
For battery systems, the LM2663 uses an external Shutdown (SD) pin to reduce the quiescent current to 10 µA.
Where can this voltage converter be used?
It is suitable for applications like laptop computers and medical instruments.
What are the recommended conditions when operating at high temperatures?
For temperatures above 85˚C, do not short OUT to GND or V+, as the device may be damaged.
How can I modify the oscillator frequency?
The frequency can be lowered by adding an external capacitor to the OSC pin.
