Description

Voltage regulator Pololu 5759 combines an isolated DC-DC power module based on the Texas Instruments UCC33420RAQR with a step-up regulator. The module operates from a 4.5–5.5 V input and provides a regulated 12 V output with up to 100 mA of continuous current. The input and output sides are galvanically isolated, and the GNDI and GNDO grounds are not connected, helping prevent ground loops and unwanted current flow between connected circuits.

In addition to the main 12 V output, the module provides direct access to the isolated 5 V output of the UCC33420. It can supply up to 300 mA when the 12 V output is unloaded; using both outputs simultaneously reduces the available output current. Typical efficiency of the 12 V path is approximately 50%, while the step-up switching frequency is about 1.6 MHz under heavier loads.

The UCC33420 provides 3000 VRMS basic isolation and a maximum working isolation voltage of 820 VRMS. The multifunction EN/FLT pin can disable the regulator and indicate faults associated with conditions such as overtemperature or output undervoltage. The board uses 2.54 mm pitch through-holes, while a routed slot beneath the isolation IC increases the PCB creepage distance to approximately 4.9 mm.
