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.
The frequency of the built-in relaxation oscillator is set by
external components. The internal voltage regulator
provides a stable output voltage. Optimized Toko inductor
components are available.
The TK11812 is available in a miniature 6-pin SOT-23L
surface mount package.
