Programmable Synchronous Dc/dc Controller For Advanced Processors

The SC1152 is a low-cost, full featured, synchronous voltage-mode controller designed for use in single ended power supply applications where efficiency is of primary concern. Synchronous operation allows for the elimination of heat sinks in many applications. The SC1152 is ideal for implementing DC/DC converters needed to power advanced Microprocessors such as Pentium ll (Klamath), in both single and multiple pro- cessor configurations. Internal level-shift, high-side drive circuitry, and preset shoot-thru control, allows for use of inexpensive n-channel Power Switches SC1152 features include an integrated 5-bit VID DAC temperature compensated Voltage Reference triangle wave Oscillator current limit Comparator frequency shift over-current protection, and an accessible, inter- nally compensated error Amplifier Power good signal- ing, Logic compatible shutdown, and over voltage pro- tection are also provided. The SC1152 operates at a fixed 200KHz, providing an optimum compromise between efficiency, external component size, and cost. By Semtech Corporation
