5 / 21 page  5/21 XC9515 Series Test Conditions： * P_VDD1 ・2 stands for P_VDD1=P_VDD2 **Unless otherwise stated, P_VDD1 ・2=5V, VEN1=VEN2= P_VDD1・2 *** A_VSS=P_VSS1=P_VSS2=0V NOTE : *1：When the difference between the input and the output is small, some cycles may be skipped completely before current maximizes. If current is further pulled from this state, output voltage will decrease because of P-ch driver ON resistance. *2：EFFI = { ( output voltage x output current ) / ( input voltage x input current) } x 100 *3：On resistance (Ω)= (VIN - Lx pin measurement voltage) / 100mA *4：Designed value. *5：Time until it short-circuits LX1 (LX2 in the side of 2CH) with GND via 1Ωof resistor from an operational state and is set to Lx=0V from current limit pulse generating. *6：”H” is judged as “H”>VIN-0.1V, ”L” is judged as ”L”<0.1V. *7：When temperature is high, a current of approximately 20μA (maximum) may leak. *8：Current which EN1 and EN2 are measured separately. *9：Lead current which LX1 and LX2 are measured separately.
