LIN D O C #: 1825 SG1825C/SG2825C/SG3825C HIGH-SPEED CURRENT-MODE PWM T H E I N F I N I T E P O W E R O F I N N O V A T I O N NOT RECOMMENDED FOR NEW DESIGNS 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, logic, and output drivers.
