Self Biased Optical Isolator

From time to time we come across interesting products in the high
voltage area. We'll include a brief description in this high voltage
blog as we find such products.

The first item in this series is a Clare optically isolated driver
which has 3750Vrms of input-to-output isolation, and requires no
external power supply on the secondary (output) side.

The CPC1580 is an optically isolated MOSFET gate-driver integrated
circuit. The application of sufficient input LED current (2.5 to
10mA) in the CPC1580 activates the internal load-side driver
circuit. The CPC1580 uses photovoltaic cells to collect the optical
energy generated by the LED.
