LED DRIVER WITH BOOST CONVERTER CURRENT CONTROL |
摘要 |
An electronic circuit includes a driver for an LED light, having an isolated DC-DC converter having a first output at a higher voltage referred to a floating ground and a second output at a lower voltage than said first output and referred to a reference voltage. A DC-DC boost converter receives its input power from the second output of the isolated DC-DC converter and having its output coupled to the floating ground, whereby an output voltage to a LED light receives the sum of the voltages of the first output of the isolated DC-DC converter and the output of the DC-DC boost converter. |
