Descriptions:

The NJM7660D is a CMOS-based voltage converter IC designed to generate a negative voltage from a positive input supply. It is commonly used in applications requiring dual power supplies (e.g., ±5V) from a single positive source.

Features:

  • Wide Input Voltage Range (1.5V to 10V)
  • Low Quiescent Current (0.3mA typical)
  • No External Diode Required (Internal charge pump)
  • Simple External Circuitry (Only two capacitors needed)
  • High Efficiency (CMOS technology)
  • Short-Circuit Protection

This IC is widely used in analog circuits, op-amp power supplies, and other applications requiring negative voltage generation.
