SG1825C / SG2825C / SG3825C
HIGH-SPEED CURRENT-MODE PWM
PRODUCTION DATA SHEET
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, highfrequency 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.
