With an input voltage range of 36 to 75 Volts, the UHP-3.3/30-D48 delivers 30 Amps of output current from a fully regulated 3.3V output. Using both surface-mount technology and planar magnetics, these converters are manufactured on a 2.3" x 2.4" open-frame package with an industry-standard pinout configuration. UHP converters utilize a full-bridge, fixed-frequency topology along with synchronous output rectification to achieve a high efficiency of 89%. This efficiency, coupled with the open-frame package that allows unrestricted air flow, reduces internal component temperatures thereby allowing operation at elevated ambient temperatures. These DC/DC's provide output trim, sense pins and primary side on/off control (available with positive or negative logic) or sync. Standard features also include input overvoltage and undervoltage shutdown circuitry, output overvoltage protection, output short-circuit and current limiting protection and thermal shutdown. All devices meet IEC950, UL1950 and EN60950 safety standards and carry the CE mark (meet LVD) requirements).
