7 / 49 page 7/49 XCM519 Series ■ELECTRICAL CHARACTERISTICS (Continued) ● XCM519xC 1ch (DC/DC BLOCK) V DCOUT=1.8V, fOSC=1.2MHz, Ta=25℃ Test conditions: Unless otherwise stated, VIN1=5.0V, VDCOUT(E)= Nominal voltage NOTE: *1: Including hysteresis width of operating voltage. *2: EFFI = { ( output voltage×output current ) / ( input voltage×input current) }×100 *3: ON resistance (Ω)= (VIN - Lx pin measurement voltage) / 100mA *4: Design value *5: When temperature is high, a current of approximately 10μA (maximum) may leak. *6: Time until it short-circuits DCOUT with GND via 1Ωof resistor from an operational state and is set to Lx=0V from current limit pulse generating. *7: VDCOUT (E)+1.2V<2.7V, VIN=2.7V. *8: 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. *9: Current limit denotes the level of detection at peak of coil current. *10: "H"=VIN∼VIN - 1.2V, "L"=+ 0.1V ∼ - 0.1V *11: XCM519A series exclude IPFM and DLIMT_PFM because those are only for the PFM control’s functions. * The electrical characteristics above are when the other channel is in stop mode.
