DC-DC CONVERTER
FEATURES
■ Very Small Size
■ Few External Components
■ Wide Input Supply Voltage Range (1.1 to 18 V)
■ Six Selectable Output Voltages up to 32 V
■ Single Battery Cell Operation
DESCRIPTION
The TK11806 is a low power, low input voltage DC-DC
converter.
The device has been optimized for variable capacitance
diode and PIN diode bias applications. It generates DC
output voltages ranging from 9.3 V to 32 V in six steps. The
desired output voltage may be selected by simple wire
connections between control pins. The input DC voltage
can be as low as 1.1 V or as high as 18 V.
The device has a built-in relaxation oscillator. The frequency of oscillation is determined by external component
values. The TK11806 has built-in voltage reference and an
array of temperature compensated zener diodes in order to
generate various output voltages with minimum external
part count.
APPLICATIONS
■ Variable Capacitance and PIN Diode Bias
■ Portable Instrumentation
■ Radio Control Systems
■ Mobile Radios
■ Cellular Telephones
■ Cordless Telephones
■ Fiberoptic Receivers
■ Local Area Network (LAN) Receivers
■ Battery Operated Equipment
