SC1476

The SC1476 is designed as portable IMVP-IV cual phase power supply controller. With its integrated smart driver, it powers advanced pentium IV processors. It features extended intel mobile voltage positioning to increse battery life by reducing the voltage at the processor when it is heavily loaded.
SC1476 has many features. The first one is IMVP-IV compliant single chip solution. The second one is high speed hysteretic controller. The third one is selectable single / dual phase operation. The fourth one is selectable constant-ripple or constant-frequency  operation. The fifth one is selectable analog or VID controlled deepersleep setting. The sixth one is 6 bit programmable output. The seventh one is integrated drivers. The eighth one is programmable softstart. The ninth one is programmable boot voltage. The tenth one is programmable deepersleep voltage. The eleventh one is dynamic phase current matching. The twelfth one is under-voltage lock out on VccA. The thirteenth one is over voltage protection on CORE. The fourteenth one is current limit protection on CORE. And so on. That are all the main features.

Some absolute maximum ratings of SC1476 have been concluded into several points as follow. The first one is about its supply voltage which would be min -0.3V and max 7V. The second one si about its input & output voltages which would be min -0.3V and max Vcca + 0.3V. The third one is about its EN which would be max 7V. The fourth one is about its BST1 to PGND1 and BST2 to PGND2 which would be max 36V with condition of static. The fifth one is about its BST1 to DRN1 and BST2 to DRN2 which would be min -0.3V and max 7V. The sixth one is about its DRN1 to PGND1 and DRN2 to PGND2 which would be min -2V and max 30V with condition of static. And so on. For more information please contact us.
