200Volt Optically-Isolated, Self-Biased Gate Driver
CPC1590, an optically isolated MOSFET gate-driver integrated circuit which uses a bootstrap biasing technique to eliminate the load-side power supply. An external power MOSFET is controlled by the application of a low-input LED current (2.5 to 10mA) to the CPC1590, which activates the internal load-side driver circuit. The CPC1590 IC connected to the load, together with an external storage capacitor, provides bias to the internal driver circuit, which eliminates the need for a costly power supply. This device is specifically designed for low duty-cycle switching frequencies and offers isolated solid-state control to replace large modules and multi-component discrete solutions.
