SC113X bination Switching Controller and Low Dropout Regulator POWER MANAGEMENT Description Features The SC1131/2/3/4 incorporates a high current low dropout linear regulator section together with a switching voltage-mode controller. This unique bination is well suited for high current low voltage power supply applications such as the Intel Pentium TM P55, AMD K6 and the Cyrix M2 processors. The SC113X was designed to reduce the number of ponents required to design a dual power supply for multivoltage processor applications. u 85% typical efficiency for switching section u Grounded tab u 1.5, 2.5 or 3.3V @ 1% for linear section u Thermal shutdown u Internal short circuit protection (LDO) u 7 pin TO-220 package Switching Controller Section: The switching control section is a voltage mode controller designed for high current, low voltage power supply applications. Key Features include a temperature pensated voltage reference, triangular oscillator and an internally...
