DC1066A: 48V @ 5A Ideal Diode-OR Controller

DC1066A showcases the LTC4355 positive high voltage diode-OR controller and monitor in a 200W, 48V application. Included on board are two S-8 ORing MOSFETs and five LEDs to indicate a variety of fault conditions.

The 48V inputs are separated from ground and from each other with at least 60 mils spacing wherever possible. Input and output connections are made by 93 mil turrets which if removed, accommodate insertion of up to 12 gauge wire for in-situ testing.
