Description
The Pololu U5Z9F12 generates galvanically isolated 12 V from a 5 V supply. Two isolated DC/DC power modules (TI UCC33420) in series and a downstream boost regulator provide complete galvanic isolation between input and output.
Technical Specifications:
- Input voltage: 4.5–5.5 V
- 12 V output: up to 125 mA (up to 200 mA with cooling or airflow)
- Additional isolated outputs: 5 V and 10 V
- Galvanic isolation via TI UCC33420: 3000 VRMS basic isolation, 820 VRMS operating voltage
- Two UCC33420 in series, followed by a boost regulator
- Efficiency: approx. 50%
- Creepage distance on the board: 4.3 mm
- No reverse polarity protection
- Terminals on a 2.54 mm grid, input and output grounds separated (GNDI / GNDO)
- Dimensions: 11.4 × 25.4 × 3.3 mm
