Microchip MCP14T0517BT | Demoboard Isolated Bias Generator for SiC Gate Drivers

Beschreibung

The Isolated Bias Generator for SiC Gate Drivers Reference Design is based on MCP14T0517B which operatesat 5V input voltage. The board provides galvanic isolated and regulated bias voltage of +20V with respect to 0Vand -5V with respect to 0V at up to 100 mA of current. The board features configurable ENABLE pin for externalcontrol and synchronization.The MCP14T0517A/B device is a push-pull transformer driver designed for small form factor isolated powersupply applications with a switching frequency of 150 kHz for MCP14T0517A and 450 kHz for MCP14T0517B.MCP14T0517A/B allows synchronization with multiple devices and operation at higher frequencies by applyingan external clock of up to 1000 kHz.
