Two more mosfet rectifier controllers in the last few months:
LM5050 from National Semiconductor is a 6-pin orring controller introduced in Oct 2010, with functionality similar to LTC4357, but no attempt of pin-pin compatability. It adds diagnostic functions via the
6th pin. LM5050-2 data:
FAN6204 also makes a late entry from Fairchild/Samsung, an SO8 with functionality similar to ZXGD3101, with near pin-pin compatability. It prescribes external resistors to the drain voltage sensing pin. FAN6204 data:
Modeling the simple normally-off rectifier controller (or any other) becomes interesting when package parasitics are included. A T0220 or D2, for example, can show between 5 and 10nH on gate and source pins. All those spice simulations where anything happens in 10s of nanoseconds???? fugedabaddit!
