DESCRIPTION
Internal level shift and drive circuitry eliminates the need for an expensive p-channel, high-side switch. SC1101 Asynchronous Voltage Mode PWM Controller FEATURES
Low cost / small size Switch mode efficiency up to 95% 1% reference voltage accuracy Over current protection 500mA output drive SO-8 package SC1101 features include a temperature compensated voltage reference, triangle wave oscillator, current limit comparator, frequency shift over-current protection, and an internally compensated error amplifier. Pulse by pulse current limiting is implemented by sensing the differential voltage across an external resistor, or an appropriately sized PC board trace. APPLICATIONS
Pentium® P55 Core Supply Low Cost Microprocessor Supplies Peripheral Card Supplies Industrial Power Supplies High Density DC/DC Conversion The SC1101 operates at a fixed frequency of 200kHz, providing an optimum compromise between efficiency, external component size, and cost. Typical...
