Product Summary
The LM2665M6X is a CMOS charge-pump voltage converter. It operates as an input voltage doubler, +5V regulator and inverter for an input voltage in the range of +2.85V to +6.5V. Five low cost capacitors are used in this circuit to provide up to 50mA of output current at +5V (± 5%), and 15mA at -5V. The LM2685MTC operates at a 130 kHz switching frequency to re- duce output resistance and voltage ripple. With an operating current of only 800μA (operating efficiency greater than 80% with most loads) and 6μA typical shutdown current, the LM2665M6X is ideal for use in battery powered systems. The device is in a small 14-pin TSSOP package. The applications of the LM2665M6X include Cellular phones, PDAs, Handheld instrumentation and 3.3V to 5V voltage conversion applications.
