SI9112DY-E3 Description

Short technical summary and product information.

The Vishay Dale SI9112DY-E3 is a high-voltage switchmode controller designed for use in high-efficiency switchmode power converters. It operates over a wide input voltage range of 9V to 80VDC and utilizes current-mode PWM control circuitry.

 

This controller features a high-speed, source-sink output drive and an internal oscillator operating at 1 MHz. It supports various single-ended power converter topologies, including flyback, forward, and Cuk converters, when combined with an output MOSFET and transformer. The device is suitable for step-up/step-down functions.

 

Packaged in a 14-SOIC surface-mount package, the SI9112DY-E3 is specified for an industrial operating temperature range of -40°C to 85°C. Its control features include Enable and Reset functions, and it operates with a switching frequency range of 40 kHz to 1 MHz.
