SC1460CSK

The SC1460CSK is designed as a versatile charge pump for using in battery operated power supply applications requiring up to 5mA. It enables a simple low current boost circuit to be implemented without the costly inductors or capacitors associated with regular switching circuits. Applications include handheld power supplies, PDA power supplies, notebook power supplies, peripheral card supplies, industrial power supplies and high density DC/DC conversion.

SC1460CSK has three features. (1)Small size: SOT-23 package. (2)4% voltage accuracy. (3)Typical 100uAquiescent current. Those are all the main features.

Some absolute maximum ratings of SC1460CSK have been concluded into several points as follow. (1)Its supply voltage would be from -0.3V to 4V. (2)Its output voltage would be from -0.3V to 6.0V. (3)Its thermal resistance junction to ambient would be 410°C/W. (4)Its operating temperature range would be from 0°C to 70°C. (5)Its junction temperature range would be from 0°C to 125°C. (6)Its storage temperature range would be from -65°C to 150°C. (7)Its lead temperature soldering 10 seconds would be 300°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of SC1460CSK are concluded as follow. (1)Its input supply voltage would be min 2.25V and max 3.63V. (2)Its input supply current would be typ 100uA and max 150uA. (3)Its output voltage would be min -4% and max 4%. (4)Its output ripple (pk-pk) would be typ 50mV with test conditions of Io=4mA, Cout=47nF. (5)Its output current would be min 4mA and typ 5mA. (6)Its efficiency would be min 50% and typ 56%. (7)Its time to regulation at turn-on would be typ 100us. (8)Its oscillator frequency would be typ 8MHz at Vin=2.5V and would be typ 8.75MHz at Vin=3.3V. And so on.
