1-µA Typical Shutdown Current

The LM2664 CMOS charge-pump voltage converter inverts a positive voltage in the range of 1.8 V to 5.5 V to the corresponding negative voltage of −1.8 V to −5.5 V. The device uses two low-cost capacitors to provide up to 40 mA of output current.

The LM2664 operates at 160-kHz oscillator frequency to reduce output resistance and voltage ripple. With an operating current of only 220 µA (operating efficiency greater than 91% with most loads) and 1-µA typical shutdown current, the LM2664 provides ideal performance for battery-powered systems.

LM2661-3-4EVAL — 開關電容器電壓轉換器

LM2661、LM2663 和 LM2664 是屬於 CMOS 電荷泵電壓轉換器系列的一部分 (表2)。每個都使用兩個小電容器來實現電壓反轉或使電壓倍增，而沒有以電感器為主的轉換器成本、尺寸和 EMI。每部裝置都具備關機功能，而 LM2661 和 LM2663 也提供從外部來源執行時脈振盪器的能力。您也可以在 LM2661 和 LM2663 上使用外部電容器來減緩時脈速度。這些電路的小尺寸和小體積使其對行動電話、筆記型電腦、運算放大器電源、介面電源供應、醫療儀器、PDA 和手持儀器都具有吸引力。
