UNISEM US3027

The US3027 controller IC is specifically designed to meet VRM 9.0 specification for next generation microprocessor applications requiring multiple on board regulators . The US3027 provides a single chip controller IC for the Vcore , 3LDO controllers, one with the automatic select pin that connects to the TYPE DETECT pin of the AGP slot for the AGP Vddq supply, one for GTL+ and the other for the 1.8V chip set regulator as required for the next generation PC applications. The US3027 is designed to use either Bipolar transistors for Vout3(1.5V) and Vout4(1.8V) or if Vaux pin is connected to 12V, then MOSFETs can also be used as external pass elements.
