US3007 General Description
The US3007 controller IC is specifically designed to meet Intel specification for Pentium IIä microprocessor applications
as well as the next generation of P6 family processors. The US3007 provides a single chip controller IC for the Vcore , LDO controller for GTL+ and an internal 200mA regulator for clock supply which are required for the Pentium II applications.
It also contains a switching controller to convert 5V to 3.3V regulator for an on board applications that either uses AT type power supply or it is desired not to rely on the ATX power supply's 3.3V output. These devices feature a patented topology that in combination with a few external components as shown in the typical application circuit ,will provide in excess of 14A of output current for an on- board DC/DC converter while automatically providing the right output voltage via the 5 bit internal DAC .The US3007 also features, loss less current sensing for both switchers by using the Rds-on of the high side Power MOSFET as the sensing resistor, internal current limiting for the clock supply, a Power Good window comparator that switches its open collector output low when any one of the outputs is outside of a pre programmed window. Other features of the device are ; Undervoltage lockout for both 5V and 12V supplies, an external programmable soft
start function , programming the oscillator frequency via
an external resistor, OVP circuitry for both switcher outputs
and an internal thermal shutdown.
