The UM300 Series from Universal Microelectronics is a family of regulated DC‑DC converter modules offering up to 60 % efficiency and 500 VDC isolation. The series includes a range of input and output voltage options, with both single‑output and dual‑output versions.
Key data include a minimum switching frequency of 20 kHz, ripple and noise performance measured over a 20 MHz bandwidth, and compact dimensions of 2 × 2 × 0.4 in (50.8 × 50.8 × 10.2 mm). Pin‑out options are provided in standard and alternate configurations, the latter selectable by adding an “S” suffix to the model number.
