| TK11806 DC-DC CONVERTER FEATURES s s s s s 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 APPLICATIONS s s s s s s s s s 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 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. The device is available in an 8-lead plastic surface mount package (MFP-8). External inductive components are also available from TOKO.
