The US3010 family of controller ICs are specifically designed to meet Intel specification for Pentium IITM and Pentium ProTM microprocessor applications as well as the next generation P6 family processors. These products feature a patented topology that in combination with a few external components as shown in the typical application circuit ,will provide in excess of 16A of output current for an on- board DC/DC converter while automatically providing the right output voltage via the 5 bit internal DAC .These devices also feature, loss less current sensing by using the Rds-on of the high side Power MOSFET as the sensing resistor, a Power Good window comparator that switches its open collector output low when the output is outside of a 10% window and an OVP output. Other features of the device are ; Undervoltage lockout for both 5V and 12V supplies , an external programmable soft start function as well as programming the oscillator frequency by using an external capacitor.
