UCQ-3.3/35-D24PB-C

Single Output UCQ Models www.murata-ps.com Low-Profile, Quarter Brick, 8.3-40 Amp Isolated DC-DC Converters Typical units FEATURES PRODUCT OVERVIEW „„ Standard quarter-brick package/pinout For applications requiring improved electrical and thermal performance at reduced cost, consider Murata Power Solutions’ new UCQ series “quarter brick” DC-DC power converters. These compact units measure just 1.45" x 2.3" x 0.4" (36.8 x 60.9 x 10.2 mm) and fit the industry-standard footprint. Available outputs range between 1.2V @ 30 Amps to 15V @ 6.7 Amps and accept a wide input range. The UCQ’s interleaved, synchronous-rectifier topology offers high efficiency (up to 93%), tight line and load regulation, low noise and fast step response. A single-board optimized open-frame design contributes to impressive thermal operation. UCQ’s will operate up to +70°C and 100 LFM airflow with no derating. „„ Low cost; Low profile, 0.4" (10.2mm) „„ 24V or 48V nominal input „„ Outputs: 1.2V to 15V „„ Interleaved synchronous-rectifier topology • Ultra high efficiency • No output reverse conduction „„ Outstanding thermal performance „„ On/off control, trim & sense functions „„ Fully isolated, 2250Vdc (BASIC) „„ Output overvoltage protection „„ Fully I/O protected; Thermal shutdown The UCQ’s feature full isolation to 2250Vdc meeting BASIC insulation requirements of UL/EN/IEC 60950-1. Input filters reduce propagated switching noise back to input sources. Also included is a remote On/Off switch control (with positive or negative logic), output trim adjustable over nominal and output sense functions to reduce power lead losses. Extensive protection items avoid damage from out of limit voltages, currents and temperatures. Protection faults automatically recover using the hiccup technique. Besides safety testing to 60950‑1, certifications for the UCQ include application for EMC compliance (to EN55022/ CISPR22 with filter), qualification testing. „„ Designed to meet UL/EN/IEC60950-1 safety approvals +SENSE (7) +VOUT (8) +VIN (1) SWITCH CONTROL –VOUT (4) –VIN (3) –SENSE (5) PWM CONTROLLER REMOTE ON/OFF CONTROL* (2) INPUT UNDERVOLTAGE, INPUT OVERVOLTAGE, AND OUTPUT OVERVOLTAGE COMPARATORS For full details go to www.murata-ps.com/rohs OPTO ISOLATION REFERENCE & ERROR AMP VOUT TRIM (6) * Can be ordered with positive (standard) or negative (optional) polarity.
