LM2664M6/NOPB, DC-DC преобразователь, SWITCH CAP [SOT23-6]
The LM2664M6/NOPB is a Switched Capacitor Voltage Converter inverts a positive voltage in the range of 1.8V to 5.5V to the corresponding negative voltage of -1.8V to -5.5V. The converter uses two capacitors to provide up to 40mA of output current. The LM2664 operates at 160kHz oscillator frequency to reduce output resistance and voltage ripple. With an operating current of only 220µA (operating efficiency greater than 91% with most loads) and 1µA typical shutdown current, the converter provides ideal performance for battery-powered systems.
