The SG3548N is a high-performance pulse-width modulation (PWM) voltage-mode controller designed for use in off-line and DC-to-DC fixed-frequency current-mode control schemes with a minimal external parts count. It features an improved transient response, low start-up current, and a precision reference with under voltage lockout.
