The Siemens SC1101CS is a versatile and low-cost voltage-mode Pulse Width Modulation (PWM) controller designed for single-ended DC/DC power supply applications. It operates at a fixed frequency of 200kHz, offering a balance between efficiency, component size, and cost.
Key features include a temperature-compensated voltage reference with 1% accuracy, a triangle wave oscillator, current limit comparator, and frequency shift over-current protection. The device also incorporates an internally compensated error amplifier and pulse-by-pulse current limiting. Its internal level shift and drive circuitry eliminate the need for an expensive p-channel high-side switch, contributing to its compact circuit design.
The SC1101CS is housed in an SOIC-8 package, suitable for surface mount applications. Its design allows for the implementation of simple, fixed-voltage buck regulators with a minimal number of external components.
Applications for the SC1101CS include Pentium P55 core supplies, low-cost microprocessor supplies, peripheral card supplies, industrial power supplies, and high-density DC/DC conversion.
