DC1902B

DC1902B is a demonstration circuit that features the ideal diode bridge controller LT®4320 suitable for applications that require low to medium current AC to DC full-wave rectification or DC polarity correction and a small compact solution. The LT4320 drives four N-channel MOSFETs to perform full-wave rectification functionally similar to a diode bridge but with much lower power dissipation. This topology eases thermal design, and increases usable output voltage. In addition, an all N-channel topology has benefits over a P-channel topology such as a wider selection of MOSFETs, lower cost, lower RDS(ON), and smaller footprint.

• 12.046V DC input voltage, 11.977V DC output voltage and 3.5A DC load current
• 99.43% typical efficiency
