EV1320QI Datasheet, PDF (4/20 Pages) Enpirion, Inc. – The EV1320QI is a DC to DC converter specifically designed for memory termination applications.

EV1320QI
Electrical Characteristics
NOTE: AVIN = 3.3V; VDDQ = 1.5V. Minimum and Maximum values are over operating ambient temperature range unless
otherwise noted. Typical values are at T_A = 25°C.
