Datasheet

LM2664M6X/NOPB – Charge Pump Switching Regulator IC 40mA SOT-23-6

The LM2664M6X/NOPB from Texas Instruments is a compact, low-power charge pump voltage inverter that efficiently converts a positive input voltage into its corresponding negative output voltage. Designed to operate from 1.8V to 5.5V, this CMOS-based device is ideal for generating negative supply rails in portable and battery-powered systems, such as operational amplifier biasing, sensor interfaces, and mixed-signal circuits. Using only two low-cost capacitors, the LM2664 achieves up to 40mA output current with a typical conversion efficiency of 91%, providing a cost-effective and space-saving solution. It operates at a fixed 160kHz oscillator frequency, reducing output resistance and minimizing voltage ripple. The device’s low quiescent current (220uA typical) ensures high efficiency at light loads, while the shutdown current of just 1uA makes it perfect for energy-sensitive applications. Housed in a tiny 6-pin SOT-23 package, the LM2664M6X/NOPB offers simple implementation, low output impedance (12Ω typical), and robust protection for long-term reliability in compact electronic systems.

Key Features:

  • Input Voltage Range: 1.8V to 5.5V operation.
  • Inverts Input Supply Voltage: Generates negative output from a positive input (–VIN).
  • High Efficiency: Up to 91% at 40mA load current.
  • Low Output Impedance: 12ohm typical for stable, low-ripple performance.
  • Low Operating Current: 220uA typical quiescent current.
  • Ultra-Low Shutdown Current: 1uA typical for extended battery life.
  • Fixed 160kHz Switching Frequency: Ensures low ripple and compact external components.
  • Simple Two-Capacitor Design: Reduces cost and PCB area.
  • Compact Package: 6-pin SOT-23 offers high power density for space-constrained applications.
  • Applications: Negative bias generation, sensor circuits, operational amplifier drivers, and portable electronics.
