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, 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, l...
