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 fre-
quency 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.
The device is available in an 8-lead plastic surface mount
package (MFP-8).
External inductive components are also available from
TOKO.
