The SG1825C is a high-performance pulse drivers. This device can be used to width modulator optimized for high frequency implement either current mode or voltagecurrent-mode power supplies. Included in the mode switching power supplies. It also is controller are a precision voltage reference, useful as a series-resonant controller to micro power start-up circuitry, soft start, high- frequencies beyond 1MHz. The SG1825C is frequency oscillator, wideband error amplifier, specified for operation over the full military fast current limit comparator, full double-pulse ambient temperature range of -55C to suppression logic, and dual totem pole output 125C. drivers. Innovative circuit design and an The SG2825C is characterized for the advanced linear Schottky process result in industrial range of -25C to 85C, and the very short propagation delays through the SG3825C is selected for the commercial current limit comparator, logic, and output range of 0C to 70C.
