DC-DC CONVERTER
FEATURES
■ Miniature Package (SOT-23L-6)
■ Few External Components
■ Internal Rectifier and Regulator
■ Wide Input Voltage Range (1.1 to 18 V)
■ Selectable Output Voltages
■ Single Battery Cell Operation
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.
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.
APPLICATIONS
■ Variable Capacitance and PIN Diode Bias
■ Portable Instrumentation
■ Radio Control Systems
■ Mobile Radios
■ Cellular Telephones
■ Cordless Telephones
■ Fiber-Optic Receivers
■ Local Area Network (LAN) Receivers
■ Battery Operated Equipment
