Si786 Vishay Siliconix Dual-Output Power-Supply Controller FEATURES D D D D Fixed 5-V and 3.3-V Step-down Converters Less than 500-mA Quiescent Current per Converter 25-mA Shutdown Current 5.5-V to 30-V Operating Range DESCRIPTION The Si786 Dual Controller for Portable Computer Power Conversion is pin and functionally compatible with the MAX786 dual-output power supply controller for notebook computers. The device is designed as a drop-in replacement for that circuit. The circuit is a system level integration of two step-down controllers, micropower 5-V and 3.3-V linear regulators, and two comparators. The controllers perform high efficiency conversion of the battery pack energy (typically 12 V) or the output of an ac to dc wall converter (typically 18-V to 24-V dc) to 5-V and 3.
