The HPQ series DC/DC converters provide very high output current (up to 50 Amps) in an industry standard “quarter brick” package requiring no heat sink, and they are ideal for datacom and telecom systems.
The HPQ Series is an isolated high‑power quarter‑brick DC/DC converter designed for embedded systems, datacom, telecom, data‑center and test‑fixture applications. It delivers a fixed 3.3 V output at up to 50 A, offering up to 165 W total output power and a wide input range of 36‑75 V.
Key features include synchronous‑rectifier topology for high efficiency (88 % typical), no‑load operation without external components, 2250 V basic isolation, remote on/off control with selectable polarity, and extensive self‑protection such as over‑current, over‑temperature and output‑over‑voltage shutdown.
| Output Voltage | 3.3 V |
|---|---|
| Output Current | 50 A |
| Input Voltage Range | 36 V – 75 V |
| Isolation Voltage | 2250 Vdc (min) |
| Operating Temperature Range | -40 °C to +85 °C |
| Weight | 1.06 oz (30 g) |
The HPQ series can deliver up to 50 A of output current.
Polarity is set by the suffix: “P” for positive‑logic control and “N” for negative‑logic control.
The device provides at least 2250 Vdc isolation between input and output.
No heat sink is required; the converter operates from –40 °C to +85 °C without one.
