常見問題解答

What is LMC7660IN?

The LMC7660IN is a CMOS voltage converter IC designed by Texas Instruments. It is commonly used to generate a negative voltage from a positive input voltage, making it useful in applications where a negative supply is required.

How Does LMC7660IN Work?

The LMC7660IN operates by converting a positive input voltage to a corresponding negative output voltage using charge-pump technology. By doubling the input voltage magnitude and inverting its polarity, the LMC7660IN effectively creates a negative voltage output. This is particularly useful in circuits that require both positive and negative supply voltages.

How Many Pins does LMC7660IN have and What are the Functions of the Pinout Configuration?

The LMC7660IN is housed in an 8-pin PDIP (Plastic Dual In-Line Package) or SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

V+: Positive supply voltage input.
V-: Negative supply voltage output.
GND: Ground reference.
C1+: Positive flying capacitor pin.
C1-: Negative flying capacitor pin.
C2+: Positive flying capacitor pin.
C2-: Negative flying capacitor pin.
OSC: Oscillator pin for internal clock generation.

What are the Pros and Cons of LMC7660IN?

Pros:

Simple Design: Provides an easy solution for generating negative voltages from positive supplies.
Low Cost: Offers a cost-effective option for applications requiring a negative voltage source.
Compact Package: Available in space-efficient PDIP or SOIC packages for versatility.
Wide Voltage Range: Supports a wide input voltage range for flexibility in various applications.

Cons:

Limited Output Current: May not be suitable for high-current applications.
Output Ripple: The charge-pump design may introduce some output ripple voltage.
External Capacitors: Requires external capacitors for proper operation, which may increase component count.

Are There Any Equivalents/Alternatives to LMC7660IN for Recommendation?

The ICL7660 from Intersil is a comparable voltage converter IC to the LMC7660IN.
Alternatives to the LMC7660IN include the MAX660 from Maxim Integrated and the TPS60403 from Texas Instruments.
