6 / 22 page  Electrical Specifications (cont.) Specifications apply over all line, trim and load conditions, internal temperature TINT = 25ºC, unless otherwise noted. Boldface specifications apply over the temperature range specified by the product grade. Attribute Symbol Conditions / Notes Min Typ Max Unit Power Output Specifications (Cont.) Output capacitance (external) COUT-EXT Excludes component temperature coefficient. For load transients that remain > 5% rated load 1000 10000 µF Output capacitance (external) COUT-EXT- TRANSIENT Excludes component temperature coefficient. For load transients down to 0% rated load 8000 10000 µF Output capacitance, ESR (ext.) RCOUT-EXT At 10 kHz, excludes component tolerances 10 m Ω Initialization delay tINIT See state diagram 25 40 ms Output turn-on delay tON From rising edge EN, with VDDE pre-applied. See timing diagram 200 µs Output turn-off delay tOFF From falling edge EN. See timing diagram 600 µs Soft start ramp time tSS Full load (soft-start ramp time) with minimum COUT-EXT 300 ms VOUT threshold for max rated load current VOUT-FL-THRESH During startup, VOUT must achieve this threshold before output can support full rated current 14.0 V IOUT at startup IOUT-START Max load current at startup while VOUT is below VOUT-FL-THRESH 3.08 A Monotonic soft-start threshold voltage VOUT-MONOTONIC Output voltage rise becomes monotonic with 1% of preload once it crosses VOUT-MONOTONIC 14.4 V Minimum required disabled duration tOFF-MIN This refers to the minimum time a module needs to be in the disabled state before it will attempt to start via EN 2 ms Minimum required disabled duration for predictable restart tOFF-MONOTONIC This refers to the minimum time a module needs to be in the disabled state before it is guaranteed to exhibit monotonic soft-start and have predictable startup timing 100 ms Voltage deviation (transient) %VOUT-TRANS Minimum COUT_EXT (10 ↔ 90% load step) <10 % Settling time tSETTLE 2.0 ms Powertrain Protections Input Voltage Initialization threshold VIN-INIT Threshold to start tINIT delay 75 V Input Voltage Reset threshold VIN-RESET Latching faults will clear once VIN falls below VIN-RESET 50 V Input undervoltage lockout threshold VIN-UVLO- 12 15 V Input undervoltage recovery threshold VIN-UVLO+ See Timing diagram 16 V Input overvoltage lockout threshold VIN-OVLO+ 60 V Input overvoltage recovery threshold VIN-OVLO- See Timing diagram 50 V Output overvoltage threshold VOUT-OVP Latched shutdown 35.5 V Minimum current limited VOUT VOUT-UVP Over all operating steady-state line and trim conditions 14 V Overtemperature threshold (internal) TINT-OTP 130 °C Power limit PLIM 750 W VIN overvoltage to cessation of powertrain switching tOVLO-SW Independent of fault logic 1.5 µs VIN overvoltage response time tOVLO For fault logic only 200 µs VIN undervoltage response time tUVLO 100 ms Short circuit response time tSC Powertrain on, operational state 200 µs Short circuit, or temperature fault recovery time tFAULT See Timing diagram 1 s DCM3414x50M31C2yzz DCM™ in a VIA Package Rev 1.2 vicorpower.com Page 6 of 22 03/2016 800 927.9474 |
