Description

The LM2765 CMOS charge-pump voltage converter operatesas a voltage doubler for an input voltage in the range of+1.8V to +5.5V. Two low cost capacitors and a diode areused in this circuit to provide up to 20 mA of output current.

The LM2765 operates at 50 kHz switching frequency to reduceoutput resistance and voltage ripple. With an operating current of only 130 µA (operating efficiency greater than 90%with most loads) and 0.1µA typical shutdown current, theLM2765 provides ideal performance for battery poweredsystems. The device is manufactured in a SOT-23-6 package.

Reliability Metrics

Part Number Process EFR Reject EFR Sample Size PPM LTA Rejects LTA Device Hours FITS MTTF (Hours)

LM2765M6X ABCD150 0 31520 0 0 3739000 1 1060951459

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
