The UQQ series wide input range single output DC/DC converters provide 3.3, 5, 12, 15 or 24V outputs from a 9-36V or 18-75V input.
The UQQ series from C&D provides wide‑input (9‑36 V or 8‑75 V) single‑output DC/DC converters in a compact quarter‑brick form factor. Models deliver output voltages of 3.3 V, 5 V, 2 V, 5 V or 24 V with currents from 7 A up to 25 A and efficiencies up to 9 % loss.
Key features include interleaved synchronous‑rectifier topology, full isolation up to 2250 Vdc, on/off control with optional polarity, output trim and sense functions, and comprehensive protection (over‑voltage, short‑circuit, thermal shutdown). The datasheet details mechanical dimensions, pin assignments, performance specifications, and recommended application circuitry.
| Input voltage range | 9‑36 V or 8‑75 V |
|---|---|
| Output voltages | 3.3 V, 5 V, 2 V, 5 V, 24 V |
| Output current | 7 A to 25 A |
| Efficiency | up to 9 % loss (ultra‑high efficiency) |
| Isolation voltage (basic) | 2250 Vdc |
| Package height | 0.43 in (0.92 mm) |
The converters accept either a 9‑36 V or an 8‑75 V input range depending on the model.
Available fixed output voltages are 3.3 V, 5 V, 2 V, 5 V or 24 V.
All UQQ models are fully isolated up to 2250 Vdc (basic insulation).
Add a “P” suffix to the part number for positive‑polarity control or an “N” suffix for negative‑polarity control.
