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

APPLICATION INFORMATION

HANDLING MOLDED RESIN PACKAGES

All plastic molded packages absorb some moisture from the air. If moisture absorption occurs prior to soldering the device onto the printed circuit board, increased separation of the lead from the plastic molding may occur, degrading the moisture barrier characteristics of the device. This property of plastic molding compounds should not be overlooked, particularly in the case of very small packages, where the plastic is very thin. In order to preserve the original moisture barrier properties of the package, devices are stored and shipped in moisture proof bags, filled with dry air. The bags should not be opened or damaged prior to the actual use of the devices. If this is unavoidable, the devices should be stored in a low relative humidity environment (40 to 65%) or in an enclosed environment with desiccant.
