AS7660 General Description

The ALPHA semiconductor AS7660 DC-to-DC converter will generate a negative voltage from a positive source.The AS7660 generates -5V in +5V digital systems and with two external capacitors,the device will convert a 1.2V to 12V input signal to a -1.2V to -12V level.AS7660 input can also be as low as 1.0V by commecting LV to ground.AS7660 chip contains a DC power supply regulator,RC oscillator.Voltage-level transistor,four output power MOS switches,and a unique logic element which ensures latch-up free operation.The oscillator,when unlock,oscillates at a nominal frequency of 10KHZ for input voltage for 5 volts.The frequency can be lowered by the addition of an external capacitor to the OSC terminal,or the oscillator may be overdriven by an external clock.

The AS7660 has some absolute maximum ratings.The supply voltage is +13V.The LV and OSC input voltage is 0.3V to (V+ +0.3V) for V+ <5.5V,(V+ -5.5V) to (V+ to 0.3V) for V+<5.5V.The current into LV is 20A for V+ >3.5V.The output short duration is continous.The power dissipation,plastic DIP is 375mW.Plastic SOIC is 800mW.The operating temperature range I suffix is -40 to +85.The storage temperature range is -65 to +150.The lead temperature (Soldering,10sec) is +300.

At present there is not too much information about this model.If you are willing to find more about AS7660, please pay attention to our web! We will promptly update the relevant information.
