DESCRIPTION
The SG1825C is a high-performance pulse width modulator optimized for high frequency
current-mode power supplies. Included in the controller are a precision voltage reference,
micro power start-up circuitry, soft start, high frequency oscillator, wideband error amplifier,
fast current limit comparator, full double-pulse suppression logic, and dual totem pole 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.KEY FEATURES
