DESCRIPTION  
High OFF Isolation. . . . . . . . . . . . . . . . . 1 pA max DPAD1  
Excellent Isolation between diodes. . . . . . Typical 20 fA  
Matched Capacitance  
Calogic’s ultra low leakage dual pico amp diodes out perform  
conventional diodes for applications where reverse current  
(leakage) is critical and must be kept at a minimum. The  
devices have very low capacitance and are also fast  
switching. Housed in a compact dual hermetic package and a  
plastic surface mount SO-8 this product is also available in  
chip form for hybrid uses.

XDPE15284D-0000

The XDP™ XDPE15284D is a hyper transient phase controller. Core voltage is provided by a multiphase buck converter with up to 8 synchronous-rectified channels in parallel while, a second loop provides voltage for the I/O. The XDPE15284D phase configuration is flexible in how the phases are allocated to the 2 loops. Any phase can be assigned to either loop and, the phase firing order is fully programmable to offer the ultimate in phase configuration flexibility. Typically, configurations of 8+0, 7+1, 6+2, 5+3, or 4+4 phases are supported.
