DESCRIPTION

The LT®4320/LT4320-1 are ideal diode bridge controllers that drive four N-channel MOSFETs, supporting voltage rectification from DC to 600Hz typical. By maximizing available voltage and reducing power dissipation (see thermograph comparison below), the ideal diode bridge simplifies power supply design and reduces power supply cost, especially in low voltage applications. An ideal diode bridge also eliminates thermal design problems, costly heat sinks, and greatly reduces PC board area. If the power source fails or is shorted, a fast turn-off minimizes reverse current transients. Higher frequencies of operation are possible depending on MOSFET size and operating load current. Ap...
