com 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.
SC1406A has two on-chip linear regulators which drive external PNP transistors with output voltage settings of 1.
5V and 2.
5V...
