DESCRIPTION

The US2076 is a dual function IC combining a switching controller and a 7.5A adjustable 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 ™, AMD K6™, as well as Cyrix 6X86L™ and the M2äprocessors.

FEATURES

■ The US2076 eliminates the need for a

seperate switching controller IC

■ Minimum part count allows lower system cost

■ Adjustable 7.5A LDO on board

■ 1.1V Dropout at 7.5A

■ 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: P55C™,CYRIX M2™, POWER PC™ and

AMD K6™
