Portable Pentium Ii & Iii Power Supply Controller

The SC1406 is a High Speed, High performance Hys- teretic Mode controller. It is part of a two chip solution, with the SC1405 Smart Driver, providing power to ad- vanced micro-processors. It uses a Dynamic Set Point switching technique along with an ultra-fast compara- tor to provide the control signal to an external high speed MOSFET driver. A 5-bit DAC sets the output volt- age, thus providing a voltage resolution of 25mV. SC1406 has two on-chip linear Regulators which drive external PNP Transistors with output voltage settings of 1.5V and 2.5Vdc. The linear Regulator drivers have a separate soft start. A PWRGD TTL level signal is asserted when all voltages are within specifications. The part features Low Battery Detect and Undervolt- age Lock-Out for the main Hysteretic controller to as- sure V-DC is within acceptable limits. An Over-Current Comparator disables the main controller during an overcurrent condition using an externally pro- grammable threshold. By Semtech Corporation
