The TK1181x series devices from TOKO, Inc. are DC-DC converters with miniature package (SOT-23L-6), few external components, internal rectifier and regulator, wide input voltage range (1.1 to 18 V), selectable output voltages and single battery cell operation.
The TK1181x series devices generate regulated DC output voltages ranging from 7.2 to 32 V using a built-in relaxation oscillator and internal rectifier. These converters are designed for step-up operation with an input voltage as low as 1.1 V, allowing them to operate on a single battery cell.
