Si9150 Vishay Siliconix Synchronous Buck Converter Controller FEATURES D 6- to 16.5-V Input Range (Si9150CY) D Voltage-Mode PWM Control D Low-Current Standby Mode D Enable Control D Dual 100-mA Output Drivers D 2% Band Gap Reference D Multiple Converters Easily Synchronized D Over-Current Protection DESCRIPTION The Si9150 synchronous buck regulator controller is ideally suited for high-efficiency step down converters in battery-powered equipment. Combined with the Si9943DY MOSFET half-bridge, a 90% efficient, 7.5-W, 3.3-V or 5-V power supply can be implemented using standard surfacemount assembly techniques. The wide input range allows operation from NiCd or NiMH battery packs using six to ten cells.
