SI9181DQ-50-T1 - Brand New STMicroelectronics IC Chips
-
Description
Si9181DQ-50-T1 is a current mode PWM controller for ISDN power supplies. It is designed with a 200-V depletion mode MOSFET, allowing it to power directly off the high input bus without an external start-up circuit. The input voltage thresholds for Start and Stop can be programmed within the operating input voltage range using a resistor divider. This component comes in a 14-pin SOIC package.
