DESCRIPTION

The SC1406A 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 output voltage, thus providing a voltage resolution of 25mV.

FEATURES
