The device uses two low-cost capacitors to provide up to 40 mA of output current. 91% Typical Conversion Efficiency at 40 mA 1-A Typical Shutdown Current The LM2664 operates at 160-kHz oscillator frequency to reduce output resistance and voltage ripple. With an operating current of only 220 A (operating 2 Applications efficiency greater than 91% with most loads) and 1- Cellular Phones A typical shutdown current, the LM2664 provides Pagers ideal performance for battery-powered systems.
