The Q48S25033 Series is an 82.5 W DC-DC converter in a 7.11 mm surface-mount quarter-brick, accepting 36 ~ 75 VDC and delivering a regulated 3.3 VDC at 25 A with no minimum load requirement. Output trim of -20% ~ +10% provides precise rail adjustment without board redesign. Suited to FPGA and DSP power rails that frequently idle near zero load in enterprise servers and telecom line card designs.
