Clare claimed that the optimized low gate voltage turn-on specification is ideal for applications in synchronous rectification as well as high frequency switching and power control for battery powered portable equipment.
The company said that the CPC3801N single MOSFET and the CPC3851N dual MOSFET have a current rating of 1 Ampere and 80 milliohms of on-resistance, and are ideal for solar chargers as the isolation rectifier between the solar cells and the battery.
Low voltage DC to DC converters and synchronous rectification are targeted applications, where MOSFETs can replace rectifier diodes in the output rectification circuit thereby reducing conduction losses to reduce the voltage drop to 20 millivolts for a 0.25A load, achieving a 20 times reduction of rectification power losses.
Dr Nathan Zommer, CEO of IXYS, said: “By coupling the CPC MOSFETs with our solar gate drivers the CPC1822/24, or as we call them our ‘solar bulbs’ or ‘solar panel chip’, and our SolarBits solar cells, we provide the total solution for solar chargers.”
