Fonctionnalités et applications
 

A DC to DC converter is a circuit which converts a source of direct current (DC) from one voltage level to another. It is a class of power converter.

DC to DC converters are important in portable electronic devices such as cellular phones and laptop computers, which are supplied with power from batteries primarily. Such electronic devices often contain several sub-circuits with its own voltage level requirement different than that supplied by the battery or an external supply (sometimes higher or lower than the supply voltage, and possibly even negative voltage). Additionally, the battery voltage declines as its stored power is drained. Switched DC to DC converters offer a method to increase voltage from a partially lowered battery voltage thereby saving space instead of using multiple batteries to accomplish the same thing. These products are renowned for their outstanding performance, reliability and cost-effectiveness. They are used extensively by OEMs and system integrators for  diverse applications in the communications, computing, storage, business systems, test, instrumentation, medical and industrial equipment industries.

The NJU7662 is a voltage converter incorporated CR oscillator, voltage-level-shifter and power-MOS, which generates a polarity-converted negative voltage or twofold voltage of an operating voltage ranging from +1.5 to +10V.

The application circuit of negative voltage converter requires only two capacitors, and positive twofold voltage coverter requires two capacitors, two resistors and one diode as external components.

The oscillation frequency of the internal oscillator is 10kHz and the negative voltage converter (on no-load condition) achieves extremely high-efficiency voltage conversion rate of 99.9%

The New Japon Radio NJU7662D is a DC/DC voltage converter. It comes in a 8 pin DIP package.
