The document introduces a range of power modules with different input and output voltages, including RQS and RQD series. These power modules have different output efficiency and current parameters. The document also provides detailed specifications such as input voltage range, output voltage accuracy, line and load voltage regulation, output ripple and noise, operating frequency, and efficiency for each model.
The RQS and RQD series are isolated DC/DC converters offered by RECOM. They feature internal SMD construction, optional continuous short‑circuit protection and UL94V‑0 compliant packages. The series covers a wide range of input voltages from 1.8 V to 24 V and delivers regulated output voltages up to 24 V.
The document lists core operating specifications, typical efficiency curves, pin‑out diagrams for 8‑pin and 10‑pin SMD packages, and mechanical dimensions. It also includes isolation parameters, temperature limits and package weight, helping designers select the appropriate part for their application.
