The SC1406 is a High Speed, High performance Hysteretic Mode controller. It is part of a two chip solution, with the SC1405 Smart Driver, providing power to advanced micro-processors. It uses a Dynamic Set Point switching technique along with an ultra-fast comparator to provide the control signal to an external high speed Mosfet driver. A 5-bit DAC sets the .
Low Battery Detect and Undervoltage Lock-Out for the main Hysteretic controller to assure V-DC is within acceptable limits. An Over-Current comparator disables the main controller during an overcurrent condition using an externally programmable threshold.
