Power Supply Control ICs

The Green Mode PWM-ICs have internal start-up circuits with a 500V/750V rating; low EMI noise by frequency diffusion; linearly reduced switching frequency at light load for low standby power with protection functions. The Green Mode Quasi-Resonant ICs have internal start-up circuits with a 500V rating; intermittent or linearly reduced switching frequency; and protection functions. The Power Factor Correction ICs have correspondence to a wide power range; 75W to 1kW, and achieve high power Factor ≥ 0.99.
