- **Package:** 8-pin SOIC (M)
### **Descriptions:**
The LM2660M is a versatile switched-capacitor voltage converter that can generate either a doubled or inverted output voltage from a single supply. It requires minimal external components (only two flying capacitors and two optional reservoir capacitors). The device operates efficiently across a wide input range, making it suitable for battery-powered applications.
### **Features:**
- **Simple Voltage Conversion:** Doubles or inverts input voltage with no inductors.
- **Low Power Consumption:** Ideal for portable and battery-operated devices.
- **No Diode Voltage Loss:** Unlike inductor-based converters.
- **Built-In Oscillator:** No external timing components required.
- **Shutdown Mode:** Reduces current consumption to <1µA when disabled.
- **Space-Saving Design:** Requires only capacitors for operation.
