FAQs
What is LM2663M?
The LM2663M is a CMOS voltage converter designed by Texas Instruments. It is specifically designed to generate a negative voltage from a positive voltage supply, making it ideal for applications requiring a negative voltage rail, such as op-amp circuits, portable devices, and battery-powered systems.
How Does LM2663M Work?
The LM2663M operates by using a switched capacitor charge-pump architecture to invert the input voltage and generate a negative output voltage. This negative voltage source can provide a stable and regulated supply for powering analog and digital circuits that require a negative supply rail.
How Many Pins does LM2663M have and What are the Functions of the Pinout Configuration?
The LM2663M is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- V+: Positive voltage input pin.
- V-: Negative voltage output pin.
- Ground (GND): Ground pin.
- Capacitor (C1+ and C1-): External capacitor connections for voltage conversion.
- Shutdown (SHDN): Shutdown control input pin.
What are the Pros and Cons of LM2663M?
Pros:
- Simple Design: Provides a straightforward solution for generating negative voltage rails from positive supplies.
- Low External Component Count: Requires minimal external components for generating the negative voltage output.
- Space-Efficient Package: Housed in a compact 8-pin SOIC package, suitable for space-constrained designs.
Cons:
- Output Current Limit: May have limitations on the maximum output current compared to other negative voltage regulators.
- Input Voltage Range: Limited by the input voltage range for efficient voltage conversion.
Are There Any Equivalents/Alternatives to LM2663M for Recommendation?
The ICL7660 from Maxim Integrated and the LT1054 from Analog Devices are viable alternatives to the LM2663M for generating negative voltage supplies.
