The TK1181x series devices generate DC output voltages
ranging from 7.2 to 32 V. Each device provides two
regulated output voltages selectable by a single jumper.
Designed for step-up operation, these devices will operate
with an input voltage as low as 1.1 V, thus allowing single
battery cell operation.
These converters have a built-in relaxation oscillator. The
frequency of operation is determined by external component
values. The built-in rectifier combined with an internal
temperature compensated reference allows stable output
voltages with minimal external components.
These devices are available in a miniature SOT-23L-6
surface mount package. An optimized surface mount
inductor is available from TOKO (P/N: 395GN-0091IB).
