For systems requiring controlled The world of brick DC-DC converters has seen High efficiency, up to 91% startup/shutdown, the external remote On/Off a steady size reduction. The UWS-Q12 series 9-36 Volts DC wide input range control may use an open collector switch makes another dramatic size shrink down to a transistor. sixteenth brick width (0.9 inches) while still Single output of 3.3, 5, 12, 15 or 24 Volts retaining a high power output and full 2250 Volt Many self-protection features on the UWS- Up to 54 Watts total output power DC I/O isolation. The converter family accepts 9 to Q12 series avoid both converter and external 1.30 x 0.90 x0.36 Open-frame package 36 Volts DC inputs and delivers fixed regulated circuit hazards. These include input undervoltage outputs. The UWS converters are ideal for mobile shutdown and overtemperature shutdown. The Industry standard DOSA sixteenth-brick format applications, datacom and telecom applications, output of these DC-DC converters have current and pinout cell phone towers, data centers, server farms and limit using the hiccup autorestart technique Small footprint DC-DC converter, ideal for high network repeaters. and the outputs may be short-circuited current applications The UWS outputs may be trimmed while indefinitely. Additional features include output delivering fast settling to current step loads and no Pre-bias start-up protection overvoltage and reverse conduction elimination. adverse effects from higher capacitive loads. The synchronous flyback topology yields high Trimmable outputs: 3.3Vout (10%), 5Vout, Excellent ripple and noise specifications assure efficiency for minimal heat buildup and no fan 12Vout, 15Vout and 24Vout (-20%, +10%) compatibility to circuits using CPUs, ASICs, operation. Operating temperature range -40 to +85C with programmable logic and FPGAs.
