SC1406G

The SC1406G is designed as a high speed, high performance hysteretic mode PWM controller. Teamed with the SC1405 smart driver, it powers advanced pentium II and pentium III processors. It features intel mobile voltage positioning (IMVP), which increases battery life by reducing the voltage at the processor when it is heavily loaded. It also directly supports intel's speedstep processors for even longer battery life.

SC1406G has five features. (1)High speed hysteretic controller provides high efficiency over a wide operating load range. (2)Inherently stable. (3)Compatible CPU power solution with two LDO drivers. (4)Programmable core voltage for pentium II & III processors. (5)Bative speed step support. Those are all the main features.

Some absolute maximum ratings of SC1406G have been concluded into several points as follow. (1)Its Vcc supply voltage would be from -0.3V to 7V. (2)Its low battery input would be from -0.3V to 7V. (3)Its enable would be from -0.3V to 7V. (4)Its all other I/O pins would be from GND-0.3V to Vcc+0.3V. (5)Its operating junction temperature range would be from 0°C to 125°C. (6)Its lead temperature soldering 10 seconds would be 300°C. (7)Its storage temperature range would be from -65°C to 150°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 SC1406G are concluded as follow. (1)Its input supply voltage range would be min 3.0V and typ 3.3V and max 6.0V. (2)Its operating current would be typ 4mA and max 15mA. (3)Its under voltage lock out threshold would be min 2.7V and max 2.95V. (4)Its under voltage lock out hysteresis would be min 20mV. (5)Its input high would be min 0.7Vcc. (6)Its input low would be max 0.8V. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
