1 / 16 page LM2665 www.ti.com SNVS009F – NOVEMBER 1999 – REVISED MAY 2013 LM2665 Switched Capacitor Voltage Converter Check for Samples: LM2665 1 FEATURES DESCRIPTION The LM2665 CMOS charge-pump voltage converter 2 • Doubles or Splits Input Supply Voltage operates as a voltage doubler for an input voltage in • 6-Pin SOT-23 Package the range of +2.5V to +5.5V. Two low cost capacitors • 12 Ω Typical Output Impedance and a diode (needed during start-up) are used in this circuit to provide up to 40 mA of output current. The • 90% Typical Conversion Efficiency at 40 mA LM2665 can also work as a voltage divider to split a • 1µA Typical Shutdown Current voltage in the range of +1.8V to +11V in half. The LM2665 operates at 160 kHz oscillator frequency APPLICATIONS to reduce output resistance and voltage ripple. With • Cellular Phones an operating current of only 650 µA (operating • Pagers efficiency greater than 90% with most loads) and 1µA typical shutdown current, the LM2665 provides ideal • PDAs performance for battery powered systems. The • Operational Amplifier Power Suppliers device is in a SOT-23 package. • Interface Power Suppliers • Handheld Instruments Basic Application Circuits Voltage Doubler Splitting Vin in Half 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
