The MUR range of ultrafast rectifiers from Solid State Supplies have been specifically designed to provide optimised performance of forward voltage drop with a reverse recovery time of 25ns.
The MIC2186 can be configured to operate at 100, 200 or 400kHz.
With its fixed frequency PWM architecture and easily synchronised drive, the device is ideal for noise sensitive telecomms applications.
Featuring a low current shutdown mode of 0.5uA and a programmable undervoltage lockout, the MIC2186 also has a manually selectable SKIP mode which improves efficiency in light load situations.
With a precise 1.245V reference output and selectable 50% maximum duty cycle for flyback applications, the 16-pin SOIC package operates within -40 to +85C and is suited for DC power distribution systems, wireless modems, ADSL line cards and SLIC power supplies.
