Specifications valid at 48VIN, 100% rated load and 25ºC ambient, unless otherwise indicated. Attribute Symbol Conditions / Notes Min Typ Max Unit Common Output Specifications Output power * 0 650 W Output current P ≤ 650W 53 A Output start up load of IOUT max, maximum output capacitance 15 % Effective output resistance 3.9 mΩ Line regulation (K factor) VOUT = K • VIN @ no load 0.245 0.250 0.252 Current share accuracy Full power operation; See Parallel Operation on page 16; up to 3 units 10 % Efficiency 50% load See Figure 1 97.5 97.8 % Full load See Figure 1 97.0 97.3 % Internal output inductance 1.6 nH Internal output capacitance 75 µF Load capacitance 0 3000 µF Output voltage ripple 20MHz bandwidth (Figure 17), using test circuit in Figure 25 60 150 mVp-p Output overload protection threshold Of IOUT max, will not shut down when started into max COUT and 15% load. Auto restart with duty cycle < 10% 105 150 % Overcurrent protection time constant 1.2 ms Short circuit current response time 1.5 µs Switching frequency 1.0 MHz Dynamic response – load Load change: ±25% of IOUT max, Slew rate (dI/dt) = 1A/µs See Figures 12–15 VOUT overshoot / undershoot 100 mV VOUT response time 1 µs Dynamic response – line Line step of 5V in 1µs, within VIN operating range. (CIN = 500µF, CO = 350µF) (Figure 16 illustrates similar converter response when subjected to a more severe line transient.) VOUT overshoot 1.25 V Pre-bias voltage Unit will start up into a pre-bias voltage on the output 0 15 VDC * Does not exceed IPC-9592 derating guidelines. At 70ºC ambient, full power operation may exceed IPC-9592 guidelines, but does not exceed component ratings, does not activate OTP and does not compromise reliability. |
