... UCH’s proven SMT-on-pcb designs. An optional baseplate offers full output power at maximum temperature. UCH’s feature input fi lters, input undervoltage and overvoltage lockout, output current limiting, short-circuit protection, and thermal shutdown. Additionally, all devices have output trim capability and an on/off control pin that can be ordered with either polarity ...

... Output noise may be further reduced by adding an external fi lter. Logic circuits with low power voltages may have a small voltage margin between logic ZERO and logic ONE, requiring noise sup- pression. Use only as much output fi ltering as needed to achieve your noise requirements. Excessive output capacitance can retard transient response or possibly cause instability. Low ESR ceramic capacitors may degrade dynamic performance ...

... Users should be aware however of input sources near the Under-Voltage Shutdown whose voltage decays as input current is consumed (such as ca- pacitor inputs), the converter shuts off and then restarts as the external capaci- tor recharges. Such situations could oscillate. To prevent this, make sure the operating input voltage is well above the UV Shutdown voltage AT ALL TIMES ...

... LOAD 2-3 INCHES (51-76mm) FROM MODULE Since these are isolated DC/DC converters, their outputs are “fl oating” with respect to their input. The essential feature of such isolation is ideal ZERO CURRENT FLOW between input and output. Real-world converters however do exhibit tiny leakage currents between input and output (see Specifi cations). ...

... The remote Sense lines carry very little current. They are also capacitively coupled to the output lines and therefore are in the feedback control loop to regulate and stabilize the output. As such, they are not low impedance inputs and must be treated with care in PC board layouts. Sense lines on the PCB should run adjacent to DC signals, preferably Ground ...
