For efficient, fully isolated DC power in the smallest space, DATEL's UVQ series quarter bricks offer output voltages from 1.2 to 48 Volts with currents up to 40 Amps. UVQ's operate over a wide temperature range (up to +70°C at 200 lfm airflow) at full-rated power. The optional mounting baseplate extends this to all practical temperature ranges at full power. UVQ's achieve these impressive specifications while delivering excellent electrical performance. Overall noise is 35mVp-p (3.3V models) with fast step response (down to 50μsec). These features make it an impressive product.
The UVQ Series from DATEL provides low‑profile, isolated quarter‑brick DC/DC converters with output voltages from 1.2 V to 48 V and currents up to 40 A. The converters operate from 18‑36 V or 36‑75 V nominal inputs, deliver up to 125 W, and achieve efficiencies as high as 94 % while meeting UL/IEC/EN 60950 and CSA safety approvals.
The handbook includes detailed performance tables, mechanical dimensions (with and without baseplate), pin‑out information, thermal design guidance, and an ordering guide that defines model numbers, voltage ranges, and optional features such as remote on/off control polarity and sense inputs.
