DESCRIPTION
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.
