DESCRIPTION

The US2075 is a dual function IC combining a switching controller and a 7.5A low dropout regulator all in a compact 7 pin TO220 and TO263 surface mount packages providing a total solution for dual supply processor applications such as an Intel P55C ä, AMD K6ä, as well as Cyrix 6X86Lä and the M2äprocessors.

FEATURES

■ The US2075 eliminates the need for a seperate switching controller IC

■ Minimum part count allows lower system cost

■ Fixed 3.30V/7.5A LDO on board

■ On board MOSFET driver

■ Fastest transient response of any controller method. ( 0 to 100 Duty Cycle in 100 nS )

■ 1 internal voltage reference

■ Internal Thermal shutdown

■ Internal Under Voltage Lockout protects MOSFET during start-up

APPLICATIONS

■ Dual supply low voltage processor applications, such as: P55Cä,CYRIX M2ä, POWER PCä and AMD
