DESCRIPTION

The TK11812 is a low power, low input voltage step-up DC-DC converter.

This device can be set to an output of 1.5 to 15 V DC using two resistors. The output current is dependent upon the input voltage and ranges from 8 mA at 1.6 V to 24 mA at 3.5 V. The efficiency is over 80% for an output current of 4 mA to 32 mA with a 3.5 V input and 5 V output.
