Datasheet
Datasheet Summary
Powered by GS/AI

The SI9112DY-E3 is a high-efficiency DC-DC switching controller designed for use in various power converter topologies, including flyback, forward, and Cuk configurations. It operates with an input voltage range of 9 to 80 VDC and features current-mode PWM control, which helps maintain efficiency levels above 80%. The device includes a high-voltage DMOS input and a CMOS output driver capable of driving MOSPOWER devices to deliver up to 50 W of output power. This controller is available in a 14-pin SOIC package and is specified to operate over an industrial temperature range of -40¬8C to 85¬8C. It incorporates an internal start-up circuit and oscillator with a frequency range of 40 kHz to 1 MHz. The SI9112DY-E3 also features built-in shutdown and reset functions, making it suitable for various applications requiring reliable power management. Engineers considering this product should note its low power consumption, with internal power usage less than 10 mW, and its ability to handle significant voltage variations, making it versatile for different project requirements.
