The SI9120DJ-E3 is a high-efficiency, low-power offline switchmode controller designed for use in power supplies. It operates over a wide input voltage range of 10 to 450 VDC and features current-mode PWM control, which helps maintain low quiescent current below 1.5 mA. The device can drive output MOSFETs with gate charge up to 25 nC, enabling it to deliver up to 30 W of output power at a switching frequency of 100 kHz. This integrated circuit is available in both standard and lead-free 16-pin plastic DIP and SOIC packages, suitable for industrial applications with an operating temperature range of -40¬8C to 85¬8C. The SI9120 includes an internal start-up circuit and oscillator, making it versatile for implementing single-ended power converter topologies such as flyback and forward. Engineers should note that this part is classified as obsolete, and its availability may be limited in the market.
