Pinout
Here is a brief description of its pin functions:
1. CAP+: Positive terminal for the external flying capacitor.
2. GND: Ground connection.
3. CAP-: Negative terminal for the external flying capacitor.
4. VOUT: Output voltage.
5. LV: Logic input to select between low or high voltage operation.
6. OSC: Oscillator control pin; can be used to adjust the oscillator frequency or synchronize to an external frequency.
7. VIN: Input voltage.
8. SD: Shutdown pin; when connected to ground, it disables the device and reduces the quiescent current.
These pin functions enable the LM2660MX to efficiently convert voltages in compact circuits.
