Features +5V regulated output Doubles input supply voltage TSSOP 14 package 80% typical conversion efficiency at 25mA Input voltage range of 2.85V to 6.5V Independent shutdown control pins Description The LM2686 CMOS charge-pump voltage converter operates as an input voltage doubler and a +5V regulator for an input voltage in the range of +2.85V to +6.5V. Three low cost capacitors are used in this circuit to provide up to 50mA of output current at +5.0V (± 5%). The LM2686 operates at a 130 kHz switching frequency to reduce output resistance and voltage ripple. With an operating current of only 450µA (operating efficiency greater than 80% with most loads) and 6.0µA typical shutdown current, the LM2686 is ideal for use in battery powered systems. The device is in a small 14-pin TSSOP package. Applications Cellular phones Pagers PDAs Handheld Instrumentation 3.3V to 5V Voltage Conversion Applications
