DESCRIPTION
Included in the controller are a precision voltage reference, micropower start-up circuitry, softstart, high-frequency oscillator, wideband error amplifier, fast currentlimit comparator, full double-pulse suppression logic, and dual totempole output drivers. Innovative circuit design and an advanced linear Schottky process result in very short propagation delays through the current limit comparator, logic, and output drivers. The SG1825C is specified for operation over the full military ambient temperature range of -55°C to 125°C. The SG2825C is characterized for the industrial range of -25°C to 85°C, and the SG3825C is selected for the commercial range of 0°C to 70°C.
