Vin = 12 V, Vout = 1.6 V, Iout = 60 A. 125 mV peak deviation when slewing load from no load to full load at 50 A/μsec. Oscon type low impedance caps required across output. Each phase operates at a fixed 225 kHz. Effective fundamental output frequency is 900 kHz / 4 phases each at 225 kHz interleaved. Recommended mating connector is AMP 1364125-1 or equivalent. From 5 Hz to 20 Hz, maintaining 0.02 G2/Hz from 20 Hz to 500 Hz, all axes. 6 7 8 9 Initilization level; ESD event shall cause no out-of-regulation conditions. Requires 400 LFM forced air over the converter. Ensure the thermal reference point (see figure 2) is kept below 95 ºC to maintain the reliability of the converter. The ‘Y’ suffix indicates that these parts are TSE RoHS 5/6 (non Pb-free) compliant. NOTICE: Some models do not support all options.
